Circuit Breaker Time and Motion Testing

Determining mechanical condition of high-voltage circuit breakers

BY JOZEF LEVI, Doble Engineering Company

Life expectancy of a newly installed high-voltage circuit breaker is approximately 40 years. Throughout its life, under normal circuit conditions, the circuit breaker will operate less than ten minutes. During abnormal circuit conditions, the breaker will operate less than one minute in its lifetime.

The primary goal of circuit breaker testing is to determine the condition of the circuit breaker. Breakers have...
