Transformers do not generate power — they transfer power. They can lower or raise the voltage of circuits or generators so that electric power can be transmitted over long distances. Transformers also help moderate incoming voltage to reduce or eliminate spikes in power that could damage circuitry.
There are seven different types of transformers that are used in various applications. The main types are power transformer, distribution transformer, autotransformer, isolation transformer, instrument transformer, current transformer and potential transformer.
The best way to test a transformer is with a multimeter — a device that measures electrical current, voltage and resistance. However, you should only test a transformer if you are comfortable and confident working with electrical equipment. Always remember to remove electrical power from the equipment or appliance and test in a dry area away from children and pets.
