Used Transformers

Are you looking for used transformers? Here is a list of some of the most popular kinds. These days, used transformers are being bought and sold more frequently than ever before. This is primarily due to increased demand in a range of industries. In addition to businesses, even lay individual groups have started to buy different types of used power transformers in order to address their specific requirements. In order to get a better understanding of this subject, it is important to first know what a transformer is and how it is used.

Transformers are electrical devices which adjust electricity from one particular voltage level to another so as to facilitate domestic consumption in our homes and businesses. In the United States, there are usually constructed carefully as large-sized cylinders fitted over a phone pole from which feed cables stretch directly into adjoining homes. The best thing about transformers is that they are one of the most energy-optimizing inventions of man. Most designs lose very little power during voltage changes.

Used transformers are now available in a diverse variety of options. There are used power transformers, 500 kVA transformers, high-voltage / low-voltage transformers, used current transformers, used substation transformers, used 3 phase transformers and used flyback transformers.

The most popular kinds include:

• Used Current Transformers: These are used to generate and provide current. Current transformers are used specifically to get current via the secondary circuit and measure alternate current using a conductor. They also help to transfer current smoothly without causing interference in other processes.

• Used Electric Transformers: These are used to transmit electricity from one part to the other using electromagnetic induction. Electric transformers are very popular among industries as they are sold at reasonable rates and transfer current in an extremely efficient manner.

• Used High-Voltage Transformers: These are used in applications requiring high-voltages, and also for shielding-voltage circuits. A good example of this is power transmission applications. They are equipped with a fixed number of conventional attributes and must be used with a great deal of care and expertise.

• Used Isolating Transformers: These isolate voltages instead of transmitting them. It simply separates the premise's electrical system from the monitor by sitting between them.

Most of these are sold at affordable prices, which is why buying and selling used transformers is not a very difficult task. This, however, does not mean that inferior quality is acceptable. It only means that people buy used transformers for a specific purpose which might be different from orthodox requirements.

Rewiring Your Home Electrical System

One of the first things you need to consider when you are planning a home renovation is the existing electrical system. Is the condition of the existing electrical wiring and the capacity (in amps) of the system up to code? Along with plumbing and heating and cooling systems, updating the electrical system in a house will be one of the most expensive remodeling tasks. Major electrical rewiring will require you to use the services of a licensed electrician. There are situations where you can do some of the electrical work yourself with a proper permit having your work certified by a licensed electrical inspector. You need to check your local building codes before you begin.

Electrical System Components

There are a few main components of a residential electrical system. The service entrance and the main circuit panel are the most important elements of the system. Depending on the complexity of the wiring circuits, additional auxiliary circuit panels may be required. The current National Electrical Code recommends a minimum 100 amp incoming electrical service. If your service panel provides less, it should be upgraded to the minimum or higher amperage to meet the needs of modern electrical loads. Most new homes are wired with 200 amp service. Many times the old service panels do not provide adequate grounding, so if you are keeping your existing panel it should be thoroughly checked out by an electrician.

Aluminum vs. Copper Wiring

The actual electrical wire running through your home that makes up each circuit can be aluminum or copper. Older homes and some homes constructed during the 70's and early 80's used aluminum wiring. Modern building codes in most communities do not allow aluminum wiring to be used. There are a number of reasons for this. Aluminum and copper both expand and contract when heated. Aluminum, unlike copper, has a tendency to lose some tightness with each cycle. It can invite corrosion when contacting certain types of metal and this corrosion will increase the resistance of the connection. Fire hazard is the main concern with aluminum.

There are ways to make aluminum safe, but we will cover that in another article. Solid copper wiring is the material of choice for new homes or renovations. Although 14-gage wire is allowed for many circuits, it's recommended you install 12-gage wiring, which costs a little more but can handle more electrical current, making it safer and more energy-efficient.

If you are renovating a very old home and the wiring has cloth insulation or if the insulation is brittle and cracked, you will need to completely replace it with new copper wiring. This requires removing wall covering material down to the studs. It's a big job. You should get estimates from a reputable electrical contractor. Most older homes have a very limited number of outlets in each room. Be sure to take the time to plan for any new outlets you will want with their corresponding wiring at this time. Once the wiring is in place you can complete the rebuild yourself if you feel you have the required skills.

Replacing Components

If you are satisfied with the size of the system, the number of outlets, switches and circuits, (make sure you are happy with the 240 volt outlet number and locations, if any) then you won't have to add any new circuits to the electrical system. You will just need to update and replace components of the system. Turn off the main breaker switch before doing any inspections of your electrical system. Pull the cover plates on your outlet boxes and switches and inspect the box itself. If it is intact and adequately secured to the wall and ceiling studs they will most likely not have to be replaced. Note that if you plan on adding ceiling fans to rooms you will likely need to either add bracing to that outlet box or replace it with one that is designed to accept a fan.

If your outlets are the old two prong style you will need to replace them with the grounded three prong type. It is a good idea to replace all the outlets and switches in the house. Most municipal codes will require you to use a GFCI (ground fault circuit interrupter) type outlet in the bathroom, kitchen and any other wet areas that are in close proximity to water.

There are a lot of things a homeowner can do to determine just how big a project her or his electrical rework will be. Determining the size of the system you have and the condition of your wiring and other components and developing a plan for any new outlets and circuits you many require will go a long way in planning your budget for a home electrical system update.

An Electrician Talks About Commercial Electrical Work

Hiring the right electrician takes some time. However, it is necessary to make sure the person has the right skills and experience to complete the job correctly. Making sure your building is safe with quality electrical work is important. Do not make the mistake of hiring someone who is offering a great deal but may not know how to properly do the work you are looking for.

Residential electrical work differs greatly from commercial electrical work. An electrician may specialize in one area or all areas. Many local governments mandate that businesses must hire a licensed electrician when doing any electrical work in commercial buildings, especially those used by the public.

Commercial buildings, including industrial buildings, have different rules, regulations and codes that a business must comply with. If you make the mistake of hiring an electrician who specializes in just residential electrical work or is not familiar with all the various codes and regulations, then you could be facing huge liability issues if someone gets hurt.

An electrician working on a commercial or industrial building must be able to correctly size loads. Electrical systems can easily be overloaded in buildings if the all the components are not properly wired for use.

Fire safety is an important component of the electrical system in commercial or industrial buildings. Smoke detectors must be hardwired into a power source. The detectors must also have a battery back-up in case something happens to the power source. Fire alarms also must have the correct wiring in case a fire does occur.

Back-up and emergency lighting is something many commercial and industrial buildings are required to have. There are different types of electrical lights as well as different types of power sources, such generators, to power important equipment if the power does go out. The back-up lighting systems must be properly installed and maintained to ensure they work if an emergency does occur.

If an electrician is turning a residential building into a commercial building, he or she must be aware of any ADA (American Disability Act) requirements about accessibility as well as any zoning laws. These requirements must be met before the building can be opened to employees and the public.

Any type of electrician you hire must keep up on the latest changes in the industry. Since there are some great differences in residential and commercial electrical work, it is essential you hire an electrician who has the right experience, knowledge and qualifications for your project.

Benefits Of A Residential Generator Diesel

Kohler residential generators are usually used for one of two reasons. Either there is no regular electricity source available, people need to keep things operating in case of a blackout or, there is a life-support system in the home that must be kept active at all times. With this type of generator electrical failure is not a concern for the owner.

Many people live in regions that suffer from power disruption as a result of storm activities. Tornadoes, snow, ice storms and other types of damaging weather can lead to sudden, and lengthy, power disruption that can be costly. This disruption in electricity can cause a number of problems in the household.

When the disruption lasts longer than a few hours, an individual may find that their inoperable refrigerator or freezer is full of food that must be thrown away. In addition the lack of lights and heat can be very uncomfortable. The right can keep you from being in this kind of situation.

You may also need to have an electrician run the correct type of wiring from the generator to the main power box or items that you wish to keep running during a disruption in power. In some areas, homes are equipped with the necessary wiring and location for this equipment and it is only necessary to have a qualified technician check all connections to be sure they have been properly installed.

Many individuals have an automatic transfer switch installed with the equipment to assure that they will not lose power for critical appliances or health equipment when there is a power disruption. Some communities have building codes regarding the installation of Kohler residential generators, and you will want to be sure that your installation technician is certified and knowledgeable about these code.

6 Tips to Find Qualified and Reliable Electricians

If you are experiencing electrical issues and at the same time, do not have a local electrician in you call list, then this article will share 6 simple ways to help you find the best electrician in your suburb. Follow these 6 steps and you will avoid any potential problems.

Homemade Electricity

Every day, most of us use electric energy, whether or not by the usage of handy Audio players, laptops, music systems, televisions or perhaps huge home heating system and air conditioning systems. Most of us require and consume power, but many people have never considered producing “homemade electrical power.”

Can you make your personal electric generator? Is that even achievable? Yes. But before we check out the “hows” and “whys”, let's talk about electricity.

Electricity is a form of energy exactly like heat as well as light. Naturally occurring electric sources, however, are hard to find, and most only create little or no electrical power. Take for example the static electricity which makes your arm hair stand up in an air-conditioned place. Fortunately, one simple law regarding energy is that it can be converted from one form to a different one. Consequently, our electric energy is simply a product of converting any power source to electricity. And simply because of that, we can miniaturize electric power creation.

The most common way to produce homemade electrical power is through using a solar panel. Solar panels comprise of photovoltaic cells, or even essentially, light energy to electricity converters. Light rays coming from the sun activate the photovoltaic cells that make voltage. The voltage created from each cell is comparatively small. Because of this, cells are generally connected in series or perhaps parallel to be able to produce the required voltage amount. Certainly, solar panels have drawbacks. First is that they are certainly expensive to buy. Next, they have a very low efficiency rating when compared with various other electric generators. If you want to generate your homemade electricity employing solar panels, simply prepare your wallet.

Another common solution to make homemade electricity is to turn wind to electrical energy. A wind generator is used for this process. Essentially, a wind power generator is a dynamo (the typical term for any kind of motor or electrical generator) connected to a turbine that's rotated by the push of the wind. The turbine gathers the wind power, as the dynamo converts the mechanical force of the blowing wind to electrical power. As expressed above, a dynamo is a basic term for a motor. If a dynamo turns electrical energy to mechanical energy, it's a motor. If it turns mechanical energy to electrical energy, it is a electrical generator. In comparison to solar panels, wind generators give a fairly higher effectiveness. Nevertheless, the wind turbine has to be focused where the wind is most powerful for much better electric generation.

Both solar panels plus wind generators won't develop electrical energy when there is no sunlight as well as wind respectively. Keeping their developed energy in a battery is one solution to this difficulty. Care must be correctly observed when utilizing batteries, particularly those with high “mAh” ratings. When short-circuited, they are able to produce fatal amounts of current.

There are several worthwhile choices for making your personal home made electricity. This is a matter of some on-line research, a little trial-and-error, and lastly a little determination before you may deliver valuable levels of electric energy. Just remember to take basic safety measures while working with electrical energy. You don't want to fry your Mp3 player, or a whole lot worse – fry yourself!

Power Surge and Protectors

If your home is anything like mine you probably have a small fortune invested in electronics, such as LCD, LED, or Plasma TV's, stereo and home theater equipment, gaming consoles, computer desk-tops, laptops, printers, scanners, faxes, and well the list goes on and on. So of course, you would not risk damaging any of your expensive electronics simply by not protecting them from a possible but more likely probable power surge.

Why are sudden power surges damaging to our computers and other high-end electronics. Well our homes are wired at the standard 120 voltage of alternating current. Our larger motor driven appliance frequently will peak above what is recommended for our sensitive electronic equipment. Our computers and other electronics operate best with a steady flow of voltage and not to exceed a specific voltage spike.

Surge protector power strips are one way to protect your electronics from power surges. Many of us think damaging power surges only occur when lightning strikes, or when a power outage occurs. Although, a lightning strike would be extremely damaging, it is also the most unlikely to happen.

So where will these power surges come from, and what effect do they have on your computer and expensive electronic gadgets.

A frequent source of power surges are coming from your own home, your air-conditioner, refrigerator and other high powered appliances and equipment kick on and off and cause sudden power demands on the electrical system and disrupt the steady voltage flow to your electronics. Faulty wiring in your home can also cause power surges in addition to your utility company's power equipment.

Our computers and electronics today contain many sensitive components such as microprocessors, which are extremely susceptible to damage from power surges. Even small frequent power surges can wear on your electronics internal components decreasing their life span significantly.

Surge protectors are a means of protecting your expensive electronics and computers. In addition to surge protectors it is important to regularly, backup your computers files, pictures and anything else that you cannot afford to lose if your computer crashes.

What type of surge protection is available, and what to look for when choosing a surge protector.

The most widely used surge protectors use the metal oxide varistor or (MOV) the spiked voltage diverts to the surge protectors grounding line. Another type of surge protection device known as a gas discharge arrestor, utilizes the gas as a conductor to the grounding wire.

The Joule rating describes the amount of energy the surge protector can absorb before failure. Your telephone and coaxial cable should be protected from power surges as well, so look for the extra connections on your surge protector. An indicator light on the strip will alert you of surge protection failure. This is an important feature because if the surge protection fails the strip will still provide power to your electronics but would not be protecting them from any power spike.

When choosing a surge protector verify the UL rating and check the length of warranty.

Finally, technology is moving and changing at an astronomical rate. As perceptive and savvy consumers, it makes sense to stay educated on today and tomorrow's technologies, it is in our best interest.

An Electrical Contractor Safely Gives You the Help You Need With Your Power Problems

Food, love, and shelter are among the basic necessities of life. No one can actually live through normal existence without those three fundamental factors. But for any person who is living in a modern city, there is one more basic need: electricity.

Modern living is tied up with electricity. Without it there would be no light, no heating or cooling, no internet, no normal modern life. Electricity, without a doubt, is vital and life-giving; yet it is also a dangerous force. It is estimated that about 25,000 people suffer serious burns due to electrical accidents and up to 1,000 individuals die from electrical injuries each year.

The vast majority of electrical injuries happen in the work place. However, there are many electrical accidents that happen in seemingly peaceful residences as well. Electricity, if not regulated properly, can be a very unpredictable and life-threatening force. A responsible homeowner, therefore, would take all available means and resources in order to ensure that his property's electrical wirings are properly and safely installed.

That task cannot be done by a handyman. Ensuring the safety of your residence is a serious matter. You should not let amateurs do the job. Don't take the risk. To ensure safety in your house, hire the services of an electrical contractor.

You may get recommendations from your neighbors or friends about a particular contractor, but it is always best to do your own research. Many people start by searching the Yellow Pages. While you may get the contact number, location, and other basic stuff about a contractor's business in the pages, you will probably not be able to acquire significant information.

It is always best to do research online. Many contractors specializing on installing electrical wirings have websites these days. But how do you narrow down your choices?

The first thing that you can do is check out how long the contractor has been doing business. In any industry, experience is very important. Long time contractors usually have vast knowledge and exceptional expertise. They may charge a bit higher than upstarts, but you can be sure that they'll do the job at an exceptionally high level of quality.

Another way to gauge a contractor's quality is to search for testimonials in his website. It is always a good sign to see several positive feedbacks from satisfied clients. But you should not stop there. You should also check if the contractor's staffs are licensed. Electricians that have met licensing standards are generally more knowledgeable than regular ones.

Finally, try emailing the electrical contractor several questions. Fast response time usually means that the contractor is intent on satisfying your needs. Watch out for one who takes a long time to send responses for he might be one of those shoddy contractors who only look to pocket a client's money.
