CB MONITOR for substation equipments is a cost-effective on line diagnostic system used to monitor MV and HV circuit breakers. CB MONITOR system can monitor up to 10 circuit breakers at the same time. The purpose of the Circuit Breaker Monitoring System is to highlight issues before these can cause an inefficiency in the system, thus allowing a far better management of condition based maintenace. CB MONITOR verifies continuously the following parameters:
