Online Circuit Breaker Monitoring System

---

ISA Advance Instruments (I) Pvt Ltd offers CB Monitor – an On Line Circuit Breaker Monitoring System. 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 inefficiency in the system, thus allowing a far better management of condition based maintenance.

CB Monitor verifies continuously the following parameters:

• Auxiliary contacts opening and closing time
• Auxiliary contacts bouncing times
• SF6 density trend
• Temperature
• Accumulated fault current during arcing time (l2t)
• Open and close current profiles
• Mechanism operating time
• Battery voltage

Then, the monitoring system through its software processes and manages the acquired data and automatically sends alarm messages to the central SCADA if thresholds are exceeded. The software can process and analize the data and automatically can detect and report in details the origin of the problem (eletrical, mechanical, aging or gas leakage), without the need of the operator's analysis.
