When Testing Circuit Breakers, Be Sure to Measure Their Motion #121

Circuit breakers are designed to safely switch the flow of electrical power under normal load conditions and quickly isolate faults and physically disconnect affected circuits within milliseconds to prevent catastrophic, widespread failures.

Because circuit breakers often remain idle for long periods of time, regular testing is essential to detect hidden degradation, such as corrosion or lubrication failure, and to ensure they operate reliably when needed during emergencies.

In this episode of Energy Talks, OMICRON circuit breaker testing experts Andreas Nenning and Elias Alber discuss the various methods for assessing the condition and reliability of circuit breakers and the frequency of measurements. More specifically, they highlight the significance of performing motion measurements on circuit breakers for identifying potential mechanical issues that can affect their reliability. Andreas and Elias also identify the evolving industrial standards that increasingly emphasize the necessity of motion measurements in circuit breaker maintenance practices.
