What is an electrical transformer? Well, chances are you’ve seen one before, possibly without knowing it. They come in all shapes and sizes and there’s likely one in your neighbourhood or possibly even in your toy train set. And no, we’re not referring to any type of extraterrestrial robot. Larger ones are usually grouped together and can often be found enclosed in isolated, fenced-off areas or power plants. Although at some point in time, you’ve probably been told not to get too close to one, their function might still be unclear. We get more in depth about their overall purpose below:

Electrical transformers are electrical devices used to transfer electricity from high voltages to low voltages and vice versa. Most electrical transformers are built for the latter. Without getting too technical, the process used to transform this energy is known as electromagnetic induction which utilizes magnetic fields throughout the process.

There are many different types of electrical transformers that serve different purposes depending on the size of the task. Everyday uses around the household may include powering appliances, equipment and even children’s toys. The power that stems from large power plants is usually too powerful for its intended use; therefore, an electrical transformer is used to downsize the electricity into an appropriate voltage that is then transferred through coils.

Aside from powering our home appliances and equipment, electrical transformers have an enormous impact on our everyday lives. Many homes and businesses aren’t located within a close enough proximity to a power plant. So how do these homes and business’s get enough energy to operate? That’s where electrical transformers come in handy. The technology behind these transformers allows them to transfer energy from far away at an impressive speed. The next time you heat up a meal in the microwave or flick on the lights in your house, you’ll know exactly where that energy came from!

Your lights are beginning to flicker. Home appliances are losing power. You’re starting to rely on candlelight more and more. But don’t worry; it’s not a sign of some poltergeist haunting your home.

Now that we’re in the midst of spring, thunderstorms are starting roll back in, ready to knock out all the electrical power in your home. You need to make sure your home’s electrical system is ready to go for the season ahead.

If you’re unsure when to call for repair, please observe the following 3 signs in your home:

GFCI stands for ground fault circuit interrupters. This specific type of outlet can help prevent most electrocutions, and are even required in homes near sinks such as those in the kitchen or bathroom. GFCI outlets measure the current flowing out of the outlet and back. If the values vary, even slightly, the outlet with shut down any transfer of electricity. This has saved thousands of lives over the last 40 years. It’s very easy and quick to have an electrician go through your home and replace standard outlets with life-saving GFCI outlets.

If you’ve ever had children, you know how important outlet covers are in the home. While they may not be necessary all the time in a home with only adults, there are many other reasons besides children that these covers come in handy. Outlet covers are simply pieces of plastic that fit into outlets to protect anything from making contact with the available electric current. These covers protect children from putting their fingers in outlets, dogs and cats from licking them, and help prevent the rare accident as well. Pick some up at your local hardware store.

If you’ve ever opened up a light switch panel, you’ve probably seen simple situations that have three wires. One wire is the hot wire which carries electricity to the outlet. The other hot wire is only hot when the switch is activated and carries the electricity to a light or appliance. The third wire is the ground wire. More often than not, especially in older houses, this third ground wire may not be attached to anything. It’s important to make sure this ground wire is properly installed to the switch to avoid things shorting out or electrical fires.

Perhaps your house was originally built without air conditioning or you have added a full laundry room onto your home that wasn’t there when the house was built. If that’s the case, you may have outgrown your home’s electrical panel without realizing it. Adding high energy use appliances can easy place an extra toll on your electrical panel. The best way to know this is if your lights flicker when you start an appliance or you have a breaker regularly flip. It’s time to call an electrician if you think this may be the case.
