4 Critical Tests for Evaluating HV Circuit Breaker Performance

Contact Timing Test. Circuit breakers are equipped with fixed and moving contacts that are housed within an arcing chamber. The moving contacts are actuated by the operating mechanism to quickly open or close the circuit. Mechanical Motion Test. Motion tests are performed using a circuit breaker motion analyzer equipped with a transducer to check the operating mechanism stroke, velocity, damping, and over-travel against the manufacturer specifications. Control Circuit Test. A circuit breaker is only as good as the system that controls its operation. Most modern circuit breakers are equipped with electronic coils that actuate mechanisms responsible for opening and closing the main contacts. Dynamic Resistance Measurement (DRM) Contact wear is an important factor that can affect the performance of a circuit breaker. High resistance between the contacts and contact pitting are prime examples.
