CB MONITOR -ON LINE CIRCUIT BREAKER MONITORING SYSTEM

CB Monitor is a cost-effective on line diagnostic system specifically designed to monitor up to 10 MV and HV circuit breakers simultaneously. CB Monitor verifies continuously the following parameters:

• Auxiliary contacts opening and closing time
• Auxiliary contacts bouncing times
• SF6 Density trend (optional)
• Temperature (optional)
• Accumulated fault current during arcing time (I2t)
• Open and close current profiles
• Mechanism operating time (optional)
• Battery voltage.
