HV Circuit Breaker testing FAQs
Medium and high voltage circuit breaker testing often involves capturing the critical first trip, measuring timing, travel, coil currents, static and dynamic resistances, and performing vibration analysis. When trended over time, this data will provide a clear pattern of deviation and changes, alerting you to any problems so that you can ensure that the circuit breakers in your system never fail to operate when needed.
