Extend the Life of Your Circuit Breakers

What to ask to ensure proper circuit breaker testing and maintenance

BY ROBERT FOSTER, Megger

Protecting a utility’s assets is essential. There are many different apparatus in electrical substations that need to be protected. The circuit breaker (CB) is designed to stop the flow of electricity and protect not only your expensive assets but human lives as well. The CB lies idle most of the time, allowing current to flow continuously, but when it is...
