We rely on circuit breakers to clear faults and protect other expensive assets. Yet, under normal conditions, a breaker may only be in operation for less than ten minutes throughout its life. You test and maintain breakers so you know they can and will perform when they are needed.
Perform dielectric, timing & motion, and partial discharge testing with our diagnostic test equipment. From the M4100 and M7100 analyzers, PD surveyors like DFA300, DFA500, PD-Smart and online monitoring devices, C.N. Rood has a complete range of tools needed to assess the health and operation of circuit breakers.
