Medium voltage circuit breaker with capacitor bank supervisor.

摘要

A Medium Voltage Circuit Breaker that comprises at least a pair of contact mutually coupleable and uncoupleable to carry out opening/closing operation, a magnetic actuator operatively connected to at least one of said contacts, a capacitor bank comprising one or more capacitors that deliver power to said magnetic actuator for carrying out said opening/closing operation and a control device; the Medium Voltage Circuit Breaker further comprises a supervisor device of said capacitor bank, said supervisor device measuring the Equivalent Series Resistance and/or the Capacitance of said capacitor bank system
