CASE STUDY: DETECTING BREAKER FAILURE USING ONLINE MONITORING
A large renewable energy provider was looking for a way to avoid unplanned outages related to the circuit breakers they use daily to switch between generator and solar power at one of their locations. In the previous year, one breaker had slowed to the point that the breaker fail scheme was forced to operate, causing them to experience an outage at the plant. After performing lubrication maintenance to the breaker and bringing interrupting times back within acceptable limits, a Dynamic Ratings’ Breaker Performance Monitor (BPM) was installed in May 2021 to monitor the health of the asset.
Later that year, the monitor started to detect deviations in the trip coil waveform that slowly got worse over time.
