Solar Home Energy: What is it for? 1

Solar Home Energy: What is it for?

Solar energy—this term basically does not cause a stirring in the mind as the explanation that comes at hand is indeed too simple.

Everyone knows what is meant by solar energy, and that is,

the energy that comes from the sun. In its most basic sense,

solar energy and other solar home equipment are nonetheless environment-friendly and not risky at all.

But then you need not become one fine environmentalist first before you will be able to come across with

whatever advantageous benefit solar home energy has.

Why is the solar home energy said to be environment-friendly?

What are its general benefits?

Practically speaking, when solar home energy is used,

the electrical bills tremendously go down as compared to the other type of home energy available for all people.

Why would you pay for such expensive bills when all you need to do is to employ solar home energy?

Another major advantage of the solar home energy is the absence of the very complicated and dangerous wiring.

Solar energy lights in the garden path or any other solar energy-powered items used in your home are ready

to be installed less the wiring to be dealt with.

In reality, these solar light bulbs are equipped with darkness sensors so they need not be turned

on to give off light and they need not be turned off as well when they are no longer needed.

As a sort of simple explanation, the solar light bulbs will simply have to be purchased, taken out of the boxes,

installed, and then presto!

You just have to situate them where you want them to be and never worry about them ever again.

A List of the Benefits of Solar home Energy

Why is the solar home energy equally beneficial? Why is it more recommended for use?

Here are some of its benefits which are truly worth the attention to be graced by anyone:

Solar home energy is environmentally friendly.

As mentioned a while ago, solar home energy will not harm the environmental features.

It is specifically clean and renewable as well. More so,

it does not cause pollution just like what the rest of the traditional electrical forms do.

Solar home energy systems need the least maintenance.

They are not fuel-powered so no need to buy the refills.

Solar home energy makes you save a lot of money.

The energy that is derived from the sun can be accessed for free as you make use of solar lights,

solar panels, and the likes. The federal government most of the time gives out financial incentives.

You don’t get affected by the rise of the fuel rates since you are using solar home energy.

Making use of the solar home energy makes you entirely independent from the foreign and centralized energy sources.

Power outages will not likely affect you in any manner.

Most of the solar energy items are very easy to install thus lessening the complicated work of the wiring systems.

Some Common Disadvantages of the Solar Home Energy

Of course the disadvantages will not be taken aside.

Here are some of the most common disadvantages of the solar home energy:

The employment of a solar home energy can be expensive at first. But as time passes by,

it becomes light to the pocket.

The strength of the solar home energy will relatively depend on the location of your home in relation with its facing to the sun.

Also, the area of your home is another point to consider.

You will need large areas to install the solar panels.

Solar Home Energy: What is it for?The Various Solar Energy Items

There are lots of solar energy devices that you may opt to buy.

Included are the solar flashlights, solar heaters, car ventilators,

solar video cameras, solar radios, solar pool purifier,

solar mosquito inhibitor, solar lighting, and solar fountain pumps.

What You Must Do

Back in the earlier years,

solar energy powered devices were very costly that very few homeowners made use of the solar home energy.

But these days, small volumes of solar energy devices are put up for sale therefore making it affordable for all.

If you don’t have enough money to fund these items you can always start small.

Making Your Mobile Home Energy Efficient

If you were living on a mobile home temporarily or permanently,

you surely would want to cut down your electric consumption just like others who would like to cut down theirs.

Here are several ways in making your mobile home energy efficient:

· Improving the roof paintjob

In the hot and humid months of June, July, August, and September, mobile homes tend to heat up.

This is because mobile homes are not built with much ventilation. On regular homes,

large attics the separate the outside from the inside keep houses cool.

Vents on these attics further contribute to reduction of heat penetration to the house.

The space separating the roof of a mobile home and the ceiling is not enough to keep the inside cool.

As a result, air conditioning system works harder during hot summer days. Thus, consuming more energy.

To lessen the heat penetration to the home, cool roof coating can be done.

Do this when it is not raining since cool roof coating is water-based.

Repainting the roof of your mobile home to deflect the heat that can potentially penetrate to the inside.

· Providing better roof insulation

Many people, even a mobile home contractor would suggest that you couldn’t

do anything to improve the insulation of your mobile home.

To tell you honestly, they are totally wrong.

You can access the roof cavity from the edge of the roof that is connected with the wall or from the directly through the rooftop.

Doing so will save you as much as 15% of your total cooling system consumption.

You can do this on your own or find someone who knows how to do this.

· Maintaining a good air conditioning

Air conditioning occupies the biggest chunk of your electric bill.

This is why you need to make sure that you get the most out of it.

To so this, check your air conditioning system regularly.

You can start with the air duct. Make sure that the air duct is sealed.

Any small leak would let the outside air to enter, thus making the air conditioning to work harder.

Your mobile home’s air duct is usually located underneath.

You may want to skirt your mobile home to the ground

of few inches from the ground to protect the duct during winter and summer.

Skirting would also provide additional protection from your pets to destroy the duct.

· Air sealing your mobile home

The best way to keep the air outside from entering is to seal every spaces of your mobile home.

Windows, doors, and other openings can be sealed by weather stripping,

a rubber sealant that keeps that interior airtight.

Doing this will let the air from coming out of the mobile home.

· The mobile home location

Sitting your mobile home under the shade would let you save from air conditioning.

Since shades draw away heat even before it reaches the roof of your mobile home,

your air conditioning will not be forced to cool the interior.

· Ensuring the water heater

The water heater takes 14% of your total energy consumption.

This is the second largest energy consumer next to the air conditioning system.

If your water heater is located outside the compartment,

it surely takes additional energy load since the heat is lost because of the outside air.

You cannot cover it of course for safety purposes. Instead, you can use insulation jacket.

This will keep the heat inside the tank.

The thermostat dictates the energy consumption of the water heater.

If you have less water demand, 120 degrees Fahrenheit is sufficient enough.

For larger water consumption, 140 degrees Fahrenheit is usually required.

· Windows

Proper selection of shutters, shades, and drapes is important to keep the heat inside or away from the mobile home.

But, you have to use them properly.

Close them during the night to keep the cool air from the outside away and open it during the day if you are not using air conditioning.

Use thick shutters, shades, or drapes during winder to keep to cool air from coming in.

Consider all these to make sure you maximize the use of power in your home.

In turn, you will save money on electric bills.

Searching for Octagonal Home Energy Efficient Kits on the Internet,

the Right Way

Okay, so you decided that you want a house.

However, you do not want it to be just any house,

you want a house that won’t cost you much to maintain.

So you decide to look for energy efficient octagonal home kits. But,

wait a minute… something’s wrong.

Whenever you try typing the phrase energy efficient octagonal home kits on the internet,

no results come up.

Well, here’s what’s wrong: the error has nothing to do with the web directory you are using.

In fact, you may find that the reason why you cannot seem to find information about energy

efficient octagonal home kits is something simple.

Here’s the deal: you need to correct your spelling.

There is no such word as “efficient”. In fact, the word is actually spelled “efficient”.

This simple change of spelling can give you a lot of results on your search.

How do you prevent this from happening again? Well, you might want to expand your vocabulary.

None of us are born with the knowledge on how to spell properly.

However,

you could try to learn how words are spelled correctly.

How do you expand your vocabulary, you ask?

Well, here are some tips you can use:

1. Read – This is the best way to learn how to spell words and expand your vocabulary.

Some people actually find it boring to open up a book.

People nowadays just want to pick up the remote and turn on the TV.

Well, here’s some information for you:

you won’t learn how to spell correctly by watching television unless, of course, you are into watching Sesame Street.

Of course, no one is suggesting that you pick up the dictionary and start memorizing the spelling of each word.

What you need to do is pick up something interesting to read.

For the beginner, I wouldn’t suggest going into the complex plotlines of Robert Ludlum yet.

In order to get you started in the wonderful world of reading, you might want to pick out a book that movies are based on.

These books are often what get people started down the road of wordiness.

In time, you will find yourself reaching for books with more and more complex plotlines and words.

Because of these you will expand your word power.

2. Write – Communications nowadays are of such a high technology that we often ignore the power of the written word.

We all want to talk on the phone instead of writing a letter.

However, how else would you learn to spell correctly, if not through writing?

People may find it a bit boring. In fact, writing nowadays is mostly done through emails and text messaging.

Text messaging has also done its share of damage to people’s spelling abilities.

Nowadays, people make frequent use of “shortcuts” in their messages.

This leads to the deterioration of spelling skills all over the world.

In order to train yourself to spell properly, you’ll need to be able to take criticism for your mistakes.

You need to want to improve your spelling skills.

These tips should take you far into improving your word skills.

You next have to learn how to apply those skills to your search.

If course, when you learn about the proper spelling of words,

you won’t make the mistake of looking for energy efficient octagonal home kits. However,

there are still more mistakes that can be made on the internet.

When you search on the internet for energy efficient octagonal home kits,

you might want to prepare some standard protection like anti-virus software, anti-spyware,

popup blockers and other tools that might make your search easier and more convenient.

Another thing you should consider doing is to examine each link before you click it.

There are a lot of useless junks out in the internet and you do not want to encounter them.

In order to be able to avoid “traps” set for the unsuspecting surfer,

you need to be able to discern which websites do contain information you need and which ones are full of nonsense.

By now, though, your new love for reading will have given

you different inferences as to what signs to look for in examining information.

And that, my friend, will help you a lot in your quest.

How to Lower Home Energy Bills

We are blessed with the discovery and proper utilization of energy around us.

There are several sources of energy that makes our living easier.

Energy lights up our home every night, keeps us warm during cold winter,

allows us to be entertained, and makes our living pleasant no matter what time of the day.

And with all the other uses of energy from the moment we check our clocks in the morning to keeping

us warn as we rest during the night, all of us would agree that it would be so hard to llive without it.

We can say that we have sufficient energy supply for a lifetime but that does not mean that we are not going to conserve it.

After all, technology has its price.

And that price is something we have to pay with cash.

And if coping with electric bill is your problem every time you see your bills,

here are the ways on how to lower them:

· Provide good roof coating

A good roof coating deflects heat.

And so, insuring that the roof receives a good coating would mean insuring you that your

house would maintain good temperature on the inside.

· Keep your attic well ventilated.

Your attic is one of the more important parts of your house when it comes to the cooling system.

The attic is your first and probably the most effective part of your house the keeps the whole house cool.

But, in order for your attic to do its main purpose,

make sure that it is well insulated.

Provide vents where the heat can come out during summer.

Your attic door must also be sealed to ensure that the air from our house does not go through it and vice versa.

The attic door can be sealed with weather strippers.

· Securing all the leaks.

Leaks contribute to high cost of home energy.

Why?

It is because air from your house can easily come out from these leaks.

And the air from the outside can easily enter the house.

Both increase the workload of your heating and cooling system.

You have to remember that air moves according to air pressure and temperature.

Since the temperature of inside your house is most of the time different from the temperature outside,

air moves freely from these leaks.

Making sure that the leaks are sealed would mean less work on your heating and cooling system and lower electric bills.

Leaks would come from fireplaces, ducts, doors, ceilings, floors, walls, windows,

plumbing penetrations, electrical outlets, fans, and vents.

· Reducing the thermostat

One degree centigrade is equivalent to 5% electric bill savings. Therefore,

keeping your thermostat low will save you a lot of money.

A total saving would also come from switching your thermostat further low when you are not home or if you are sleeping.

The ideal temperature during winter is not higher than 68 degrees Fahrenheit.

· Limiting the use of water heater

The second largest electric consumer next to your heating and cooling system is your water heater.

When you wash you clothes, you don’t need to heat the water up.

Just use the water from the faucet.

This will save you by as much as 90% in washing machine energy consumption.

· Use energy efficient material around your home.

There are commercially available materials that would significantly contribute to the reduction of the cost of home energy.

One of these is energy efficient windows that deflect the outside temperature

(whether during winter or summer) from entering your home.

· Use your appliance efficiently

It is pretty basic for all of us to turn off televisions, air conditioning,

stereos and other electronic gadgets when not using them. However,

most still disregard this. The reality is;

we can save a lot if we only learn how to turn them off if not in use.

Also, small things such as iPod chargers, cellphone chargers, digital clocks,

lights and other things that seem to consume small electric current that remain plugged day

in and day out contribute to your electric bill. Making sure you unplug them would certainly

lower down your monthly electric consumption.

You have the details. All you have to do is to make sure you follow them all.

3 Basic Motion Types in a CNC Machine

CNC MachineCNC Machine A Computer Numerical Controlled (CNC) machine may have more than one motion type that it uses,

but there are three most common motion types that are easy to remember.

These are the Rapid Motion, the Straight Line Motion, and the Circular Motion.

All of these motion types may seem different but they share two things in common,

which would be that they are all modal and the endpoint of each motion is specified in motion command.

By being modal it means that the motion type would be in effect until changed otherwise.

CNC Machine

3 common motion types:

1.)Rapid Motion Type

Rapid motion type is also called Positioning.

The way this motion type is used is through utilizing the fastest rate possible of the command motion of the machine.

Example uses of rapid motion are moving to clear obstructions,

placing cutting tools to and from the desired position,

and any program that provides non-cutting in their schemes.

The command that is usually programmed to a CNC machine is G00 because in this command,

the end point for the rapid motion would be specified.

The CNC machine,

with most controls given, will be able to move as fast as possible in all commanded axes.

In the case of rapid motion, one axis may be able to reach its end point before other axes.

Straight line movement will not occur with type of rapid command function and the programmer of the machine

must take into account that there are no obstructions to avoid. Straight line motion

will happen even during rapid motion commands when done with other controls.

2.)Straight Line Motion

This type of motion would allow the programmer of the machine to command perfectly straight line movements within the machine.

Unlike the rapid motion type,

the straight line motion would allow the programmer to vary the rate of the motion or feed rate to be used during the movement.

Examples of using straight line motion would be turning a straight diameter,

taper, when milling straight surfaces,

and when drilling for this is because these examples require straight cutting movement.

The common word to specify a straight line motion into a machine would be G01,

for within this command the programmer will include the preferred end point within each of the axes.

3.)Circular Motion

This motion type would cause the machine to move in the direction of a circular path and is used to generate the radii in machining.

When talking about points on circular motion feed rate,

it is equal to that of straight line motion.

Other than that of straight line motion and rapid motion,

there are two G codes that are commonly used when programming a circular motion into a machine.

These are G02 and G03.

G02 is used when the programmer desires a clockwise motion into the machine

while G03 is used to make an anti-clockwise motion.

To know which of the commands to use,

the programmer must view the movement with the same perspective as to what the motion of the machine will be,

may it be clockwise or anti-clockwise.

Another requirement that would be programmed into a machine that would be using circular motion is that

the programmer must specify the radius of the arc that is to be generated.

With brand new technological advances in CNC, an “R” word is now used to specify the radius.

For older controls in CNC machinery, an “I”, “J”, and “K” are used to specify location of the center point of the arc.

CAM: A Vital Component of CNC

Computer Aided Manufacturing started being used by automotive and aerospace component manufacturing companies.

This sped up the manufacturing process and thus increased efficiency ratings.

However, the introduction of CAD into the industrial sector did not eliminate the need for skilled professionals.

In fact, the operation of this program requires a higher degree of skill in terms of being computer literate.

LED vs Fluorescent Tubes

LED vs Fluorescent Tubes

LED vs Fluorescent TubesFluorescent lighting has been around for over 100 years.

When compared to incandescent lighting, florescent lights have long been touted as energy-efficient

, longer-lasting, and a great way to illuminate large spaces.

However, as the Light-Emitting Diode (LED) continues to evolve,

many experts and business owners have found sound reasoning in switching to this modern lighting.

Below, our experts here at Action Services Group help explain why it may

be time for you to invest in LED technology in our latest blog LED vs. Fluorescent Tubes.

 

What Is A Linear or Tube Fluorescent Light?

Fluorescent lights are part of the High-Intensity Discharge (HID) family.

As such, they produce light through the use of a type of gas-discharge.

Fluorescent lights typically consist of a glass outer tube that encases a thinner arc

tube that is internally treated with a fluorescent coating. Within this arc tube, an inert mercury gas is contained.

When an electrical charge is supplied to the arc tube, it excites the mercury gas and releases ultraviolet (UV) radiation.

When the UV radiation interacts with the fluorescent coating, it creates light.

Standard linear fluorescent lights are typically available in tubes that measure 48- to 84 inches in length.

 

CFL: A Compact Variant

 

While modern technology has created subsets of fluorescent lighting,

it is not uncommon for users to mistake CFLs for linear fluorescent lights.

CFL, which stands for Compact Fluorescent Light, are smaller versions of the standard fluorescent lighting we are talking about.

While CFLs are available in linear shapes, they are more commonly coiled in appearance. 

LED vs. Fluorescent Tubes Cost Savings

When it comes to retrofitting an older system or installing a new one, cost savings is often one of the biggest factors.

When talking about lighting installations, the overall cost impacts

need to take into account the overall energy consumption costs as well as those related to maintenance.

Let’s take a closer look at how LED vs. fluorescent tubes stack up when it comes to cost savings.

Energy Savings

We have noted that florescent lights are considered more efficient than incandescent bulbs.

However, nothing beats the energy savings when it comes to an LED. Fluorescent lights are omnidirectional.

This means they emit light a full 360 degrees around the bulb itself.

LED lights are one-directional, meaning they emit light in a focused 110-degree area.

But what does this mean to you? Fluorescent lights will rely on the use of a reflecting plate.

This causes an immediate reduction in lighting quality by 15%.

In addition to this, a fluorescent bulb relies on heat to produce the UV radiation from mercury gases.

When light is emitted in an omnidirectional manner, it means that heat escapes from all sides as well.

This results in more power being needed to maintain the same level of lighting.

LEDs, on the other hand, do not require any heat to produce light and emit very little of it while in use.

(Want an additional cost savings? By reducing the heat emitted by your lighting sources,

you can also expect to decrease your air-conditioning use!) Additionally, fluorescent lights need time to warm up.

While today’s technology has led to the development of florescent bulbs that warm up rapidly,

they still suffer from a delay in reaching maximum illumination.

LEDs reach full illumination immediately,

meaning energy is not wasted on bringing the lamp up to the required temperature

to produce mercury gas-based UV radiation.

Because lighting accounts for almost 40% of your entire power bill,

every second you can cut down on powering light fixtures means money you save.

Based on the direction, loss of heat, and reflection reductions –

LED lights provide almost 70% more light when supplied with the same amount of energy as a fluorescent tube.

Maintenance Savings

When it comes to linear LED vs linear fluorescent lamp maintenance, LEDs again take the lead.

Fluorescent tubes typically last between 3 and 5 years.

However, because the internal ballast is rather fragile,

should that component be damaged in any way, the lamp will no longer work. Should the ballast not be damaged,

a fluorescent tube shows signs of light degradation as it nears the end of its lifespan.

As the tube begins to die, the ends will blacken and the light will flicker,

which can cause health issues for those exposed to it.

(Headaches, migraines, eye issues, and epileptic seizures are just some of the potential concerns.)

LEDs, however, last between 50,000 and 100,000 hours.

Made of more robust materials and a simple solid-state diode assembly,

LEDs are extremely durable and can withstand much more abuse and vibration than fluorescent lamps can.

In fact, some linear LED manufacturers are so confident in their durability,

they even offer a 10-year warranty on their lamps.

 

At the end of the day, whether you damage the ballast of a fluorescent tube or not,

you will need to replace it 3.5 times more often than you will need to replace an LED.

 

LED vs. Fluorescent Tubes Quality of Light

When it comes to the expected quality of LED vs fluorescent tubes, experts again recommend LEDs for all our lighting needs.

Why?

Performance

We have already discussed how robust an LED light is when compared to a fluorescent lamp.

However, the spectrum of light that is available from LEDs far exceeds what is available through its fluorescent counterpart.

Because of its inherent design, the entire color wheel is represented through the diodes used in an LED.

This allows it to produce all shades of color, including even the slightest variations between bright white and natural light.

Fluorescent lighting, however, utilizes the blue, green and red color wheel.

This gives the lighting an extremely artificial feel and has been known

to increase the likelihood of headaches and eye problems. Furthermore,

it can skew the colors of objects under them.

Depending on what your business does, this can be an issue.

Lumens

Fluorescent lights produce between 50 and 100 lumens per watt.

By comparison, LEDs can produce roughly 130 lumens per watt.

For example, a T5HO Commercial LED tube light uses only 25 watts to produce an output of 3334 lumens.

In other words, LEDs require fewer watts to produce a brighter light.

Why We Need Electricians
The man is repairing the switchboard voltage with automatic switches. Electrical background

Why We Need Electricians

Why do people need a electrician?

Most people think that when they are building a new home,

that is the only time that they would need a electrician.

But actually you need electricians for doing a lot more then that one particular job.

If you own a home and have problems with your electricity you should call a electrician.

A electrician can fix your electrical jobs safely.

It is far better to call a electrician then to try and do the job yourself and then end up doing something wrong.

If you don’t do the job right it can be dangerous and could cause a fire in your home.

And also down the road it could be costly if your have to call a electrician in to do the job right.

benefits of having electricians

Electricians are trained to know what they are doing and they can do any electrical job right.

Newer and older homes should have the electrical wiring checked out and inspected before purchasing the home.

This will save money if they find out that it is faulty or in need of updating.

A electrician will come in handy to make the wiring safe in any home.

Some people try and do electrical jobs their selves but if you do you will always wonder if you did everything right or not.

where to find

You can usually find a electrician in the phone book if you need one.

You can also find a electrician on the internet by looking through local ads.

Some people will ask around in their community if anyone would know of a good electrician.

A electrician can be found a number of ways.

By searching for a electrician like this you can save money in some cases and

find a electrician close to your home that will do good work for you.

 

A electrician can do many types of electrical jobs.

Some electricians will not only work on homes, but will also do the wiring of security systems.

It all depends on what type of electrical job you need to have done.

A electrician will do work when a new home is being built to wire it correctly.

And electricians also work on construction sites when buildings are being put up.

When picking out a electrician try and find one that is licensed, well known by others and good at what they do.

Like any professional some electricians are better and more experienced at what they do then others.

Check them out first before you hire them to do work for you.

There is nothing wrong with finding more information out about them.

Being a licensed professional is important to know if you need a job done.

It will tell you that they have had training and put in hours of schooling to know how to do the job right for you.

A electrician is a professional that we need for many jobs around our home.

They make sure that our homes are wired safely.

It is a good idea to call a licensed electrician for all the electrical jobs around our home.

When Should We Hire A Electrician

It is easy to know when we should hire an electrician.

Some of the jobs in our home are just to much for us and we don’t have the proper understanding

and knowledge of how to fix and repair them.

Electricity can be very dangerous and is not worth taking the risk of being hurt by doing

a job that you are not sure how to do in the first place.

Electrical transformers

Electrical transformers

Electrical transformers are considered one of the most important elements of the electrical network (1 phase or 3 phase), widespread and diverse in their shapes, sizes and functions.

Electrical transformers are very widespread in the electrical system due to their importance and role in electrical circuits.

Historical introduction to the electrical transformer

The English chemist Michael Faraday was the first to discover the phenomenon of mutual induction between the two separate coils located on a core made of magnetic material.

During his experiment, he began to measure the electromotive force. Electric Motive Force) is practically in one of the two coils due to the change of current in the other coil.

Transformers appeared for the first time in 1882, made of one primary (primary) winding and several secondary windings, with the aim of obtaining several values of voltages of different values.

Magnetic heart transducers began to appear

(in English: magnetic core) for the first time in 1884 AD. It is the starting year for the use of transformers in converting Electrical energy to raise the values of voltages and transmit them to long distances.

And then the Hungarian scientist “Wire” came up with the name of the transformer on these devices, And then he came up with the idea of connecting transformers in parallel,

The 3 won electrical transformer was invented by the Russian scientist “Dolev Dobrovolsky”.

Definition of electrical transformer

The converter is known as: Transformer: It is a static (non-kinetic) electrical machine that works to convert alternating current of a certain voltage to another alternating current of other voltages, and the voltages may be higher or lower with the stability of power and frequency. To carry out the transfer of electrical energy from the place of its generation to the place of consumption.

The electrical transformer can be defined in another way as an electrical machine capable of converting the electrical power entering it with a certain effort into electrical power coming out of it with a different effort, whether increase or decrease.

Magnetic Principles of Electrical Transformers

Magnetic Principles of Electrical Transformers

magnetic principles of electrical transformers, It is necessary to know the details of the magnetic effect and the field created by the passage Electric current in electrical transformers .

There are some magnetic rules and foundations that must be studied before entering into the details of transformers, So what are the magnetic principles of electrical transformers and how do they work.

magnetic effect

It results from the presence of an ordinary magnet. magnet) somewhere in the presence of what is known as a magnetic field region, It is the area where the so-called flood lines appear (in English: Flux Lines), Which consists of lines running from the north pole to the south pole of the magnet.

We can feel it and see its direction if we put iron filings near a magnet, as shown in the following picture:

the magnetic field

Magnetic field and electric current

Faraday proved that any alternating current flowing through an electric wire, It will generate a magnetic field similar to the magnetic field that arises around an ordinary magnet.

The direction of this magnetic field is determined by Fleming’s right-hand rule. Hence the term electromagnetism.

Which means that electricity and magnets have mutual and similar relationships and effects.

It is stated that we cannot obtain a strong magnetic field from ferrous magnets,

We have taken advantage of the fact that the current passing through a wire is accompanied by a magnetic field, The same principle was applied to the files,

Where the direction of the current is the same in all the windings, Hence, a strong magnetic field is generated. It is stronger than the field originating from one or two wires.

And the above happens in transformers, As the windings are wrapped around the arm of the iron core, a strong magnetic field is created in it, which represents a longitudinal section in the iron core of the transformer.

The magnetic field associated with an electric current

Magnetic driving force

There are some laws and relationships that govern the work of this magnetic field arising due to the passage of an electric current, As if an electric current passes through a coil with a number of turns N, then magnetic forces are generated, the value of which is estimated by the following relationship:

MMF = NI

And the driving force is responsible for pushing the lines of flux in the iron core. The shorter the magnetic field force pushes the flux lines, the greater the field strength.

The importance of electrical transformers,

The presence of electrical transformers in the power system is of great importance and has many uses in transmission and distribution lines, especially in household electrical appliances.

There are also electrical transformers single-sided transformers and three-faceted transformers, Follow us to learn about the importance of electrical transformers in our daily lives.

What is an electrical transformer?

An electrical transformer is defined as a static (non-moving) electrical machine whose function is to convert an alternating current of a certain voltage to another alternating current of other voltages either up or down with stability in power and frequency. The electrical transformer is used to transfer electrical energy from the places where it is generated to the places where it is consumed.

The difference between transformers, generators and motors

Although the term electromechanical Electric Machine)

Always referring to generators and engines of all kinds,

However, a transformer is also a type of electrical machine. This is because the laws that govern the work of motors, generators and transformers are the same and they are the laws of electromagnetism.

The only difference between motors and generators on the one hand and transformers on the other hand is that motors and generators rely on the principle of motion (spin) while transformers are a static electric machine that does not rotate.

Other than that, they are all subject to the laws of electromagnetism.

The importance of electrical transformers

The importance of electrical transformers mainly lies in converting the electrical power entering it with some effort into electrical capacity coming out of it with a different effort, whether it is increased or decreased.

The transformer is used as a main element in transmission lines in order to transmit electrical energy with high voltages over longitudinal distances with minimal energy losses.

Advantages of using electrical transformers

The main advantage of transformers in the electrical power system is to reduce the value of the current transmitted through lines and cables, This feature has several other advantages:

  • Minimizing the power lost during electrical power transmission.
  • Reducing the value of the drop in voltage.
  • Reducing the cost of transmission lines and electric power towers.

Conclusion: Electrical transformers have an essential role in organizing and transmitting electrical energy across transmission lines for longitudinal distances with the least possible losses in terms of voltage drop and lost capacity.

electrical transformer parts

The electrical transformer consists of several basic and simple parts, which are as follows:

  • iron heart

represents the magnetic circuit,

It consists of a group of thin sheets of magnetic iron ranging in thickness from 0.35 mm to 0.5 mm and are isolated from each other.

The plates are pressed together with nails or screws to form a suitable path for the magnetic flux lines.

  • files

The electrical circuit in a transformer, It consists of the following:

  • Primary files: It consists of coils of insulated copper wire, And connected to the electrical source.
  • Secondary files: It consists of coils of insulated copper wire, And through it provides the load with electrical energy.

How does an electrical transformer work?

The idea of working the electrical transformer is based on the principle of electromagnetic induction, which states that the value of the driving force is directly proportional to the rate of change of the magnetic flux.

Therefore, the transformer cannot be used in DC systems because it produces a constant magnetic field whose change is equal to zero.

Types of electrical transformers

Electrical transformers are classified in terms of their use into two main types:

electric hoist transformer: (in English: Step-up Transformer) These transformers are used to increase the voltage value while decreasing the current in the secondary winding for power stability,

The number of turns of the primary coil is less than the number of turns of the secondary coil.

step-down transformers: (in English: Step-down Transformer) These transformers are used to reduce the voltage value with constant power and thus increase the current value in the secondary winding,

The number of turns of the primary coil is more than the number of turns of the secondary coil.

Function of electrical transformers

Function of electrical transformers

transformer function, The presence of the electrical transformer has a major and essential role within any part of the electrical network system.

Whether it is within the generation, transmission, distribution or distribution network.

Since the primary role of electrical transformers is to lower or raise the value of voltage and current ,

Whether through transmission lines and cables or in electrical distribution lines.

Let’s get acquainted with the function of electrical transformers, And do these converters have one function, or can they be used in several different functions, depending on the nature of the network in which they are located?

The role of electrical transformers

There are many roles these transformers can fulfill, for example:

Transmission transformers that contribute significantly to the transmission of electrical energy over long distances from generating stations to transmission lines, then to distribution transformers, and finally to electrical loads.

When we want to transfer electric power from the generating station to the transmission lines without using a step-up transformer,

What happens is we’re faced with a very high current problem, Which needs an incredible number of transmission cables.

To solve the problem, a transformer must be installed. In order to raise the voltage to times the voltage generated in the generating station by 20kV/500KV (it may vary from one country to another).

As a result of what happens when the voltage is raised immediately after the generator, It is to reduce the current to the lowest possible value with constant power. Then we can use a small number of cables.

Types of electrical transformers

There are many types of transformers in terms of: uses,

number of beats, Depending on the cooling method, conversion ratio and operating frequency, But we will focus on two types in terms of the nature of use only, namely:

  • Step-down transformer: In which the voltage is raised and the current decreased with constant power. Like: transport adapters.
  • Step-down transformer: In it, the voltage is reduced while the current value is increased while the capacity is constant. Like: distribution transformers.

Function of electrical transformers

There are many different functions of transformers of different types, as we mentioned in the types of electrical transformers , and these functions include:

transmission adapters:

Its function is to raise the voltage of the electrical energy generated by the power station to multiples of the voltage generated. In order to reduce the value of the current while the generated power remains constant,

In order to reduce the power lost during electrical power transmission, It is more practical by reducing the cross-sectional area of the transmission lines.

These transformers are placed directly after the generators in the generating station.

transport adapter

Distribution Transformers: Its function is to reduce the voltage in accordance with the voltage of the electrical network feeding factories and homes. Raising the current with constant capacity.

Electrical transformer installation

transformer installation, The presence of the electrical transformer has become necessary in the electricity network, whether power electricity or home electricity,

The transformer is only a transmitter of electrical energy and not a producer of it.

Where the electrical transformer is generally used in power electrical systems to transmit power, Even in the operation of electrical devices with an appropriate voltage, it is determined by the voltage of the device.

A brief history of the electrical transformer

He was the first to discover the phenomenon of mutual induction. Mutual Induction) is Faraday in 1838,

Where he placed two separate coils on a heart made of magnetic material, He practically measured the electromotive force in one of the two coils as a result of the current in the other coil.

Transformers made from one primary winding and several secondary windings were first introduced in 1882 with the aim of obtaining different values of secondary voltages.

Magnetic core transducers are used to convert electrical energy to high efforts, And transported long distances in 1884.

Brothers John and Edward Hopkinson first made a simple transformer consisting of insulated steel plates. It has two coils, one for low voltage and the other for high voltage.

The first person to call these devices a transformer was the ductwork scientist Wiri. He later invented the idea of connecting transformers in parallel.

Finally, the Russian scientist “Dolev Dobrovolsky” invented the triple transformer in 1889.

Three phase electrical transformer

Reasons for the spread of electrical transformers

We all know that the role of the electrical transformer in transmission lines is to reduce the value of the current transmitted through lines and cables, reduce energy loss, Facilitating the transmission of electrical power.

As the generating stations produce enormous electrical energy by using several huge generators,

It is illogical to transfer this energy produced with the same voltage and high current, which requires a large and imaginary amount of cables of large diameters.

Here comes the role of the electrical transformer,

Where it works to raise the value of the voltage to double values, Like: Step up transformer 20/500 kV, It means that it is able to raise the voltage to become the transmission voltage 500kV instead of 20kV.

The purpose is to reduce the current value to the lowest possible value and therefore we need less number of cables and less diameter.

Electrical transformer installation

The electrical transformer is composed in its simplest form of an iron core. Iron Core) wrapped on both sides of the coils, They are:

Primary file: (in English: primary winding), Which is the coil that connects directly to the power source, It consists of a certain number of turns (Np).

secondary file: (in English: Secondary Winding), It is connected to the load directly on its edges or through transmission lines, It also consists of a number of turns and is denoted by the symbol (Ns).

It is considered the most important two main components in the composition of the electrical transformer, They: Iron core and coils.
