Monitoring circuit breakers: Reviewing current testing methodologies

BY FINLEY LEDBETTER, Group CBS

Circuit breakers, from low-voltage molded case to high-voltage SF6 (sulfur hexafluoride) circuit breakers, all connect and isolate electrical loads from downstream machinery. While some breakers are used as disconnect switches, they are not designed for this purpose. Most breakers are used sparingly, giving technicians few opportunities to test the breaker’s operation without removing the breaker and downstream equipment from service.

To minimize downtime,...
