What is the purpose of a current transformer? It measures alternating current flowing through a conductor. Since it is used to measure current, a current transformer is often classified as a type of instrument transformer. One could measure the voltage drop across a known resistor. This is okay for low current applications but is often impractical for high current applications. (read more)

Typical maintenance of transformers includes periodic testing of the nitrogen blanket for flammable vapors to evaluate the health of the transformer. If the testing reveals a buildup of flammable vapors, the transformer can be removed from service in a planned manner instead of a catastrophic manner (such as an explosion). (read more)
