C2 Duty Cycle Test for Circuit Breakers as per IEC 62271

The C2 Duty Cycle Test confirms a circuit breaker capable of capacitive switching operations. Even a few tens or hundreds of amperes of capacitive current may cause unexpectedly high transient recovery voltage. That is not a healthy condition for the insulation of the system. A circuit breaker interrupts capacitive current when it cuts unloaded transmission … Read more
