Have you ever wondered what happens to all that electrical power that flows through the circuits in our homes? Well, you might be surprised. Just like us, the insulation that covers the wires running through our walls ages with time. While we’d like to think that every bit of energy reaches its destination, that is often not the case. Finding out how much escapes is where Insulation Resistance Testing comes in.
Every wire in our home is protected by some type of insulation. Not all insulation used for wiring is created equal, and can decay at different rates. A crack or imperfection along the path of our circuit can allow electricity to leak. That leakage can be insignificant or it can be dangerous to our home. Electrical Insulation testing allows us to get a good idea if electricity is leaking at a small rate or at one which should have our full attention.
Insulation Resistance Testing (IR Testing) was developed in the 1900s. It is the most basic of this type of testing and continues to be used today. In simple terms, electrical insulation is tested by submitting a certain amount of voltage into the circuit and then measuring the output at the other end. While this may sound simple, it requires a professional electrician to use their mathematical skills to use those before and after numbers.
If you think your home’s electrical wiring is outdated or not working properly, and would like to have a home electrical system inspection, check out our current specials and give us a call. Douthit Electrical has been providing Charlotte with quality electrical services since 1990.
