Testing of circuit breakers is trickier as compared to other electrical equipment like transformer or mechanism because the short circuit current is very huge. Circuit Breaker Testing is used to test both the presentation of individual switching mechanisms and the timing of the in general graceful system. Circuit Breaker Testing is essential to guarantee the safe and reliable performance of this key connection in the power advantage series.
Normally the testing of circuit breakers is approved out using as a power alternator having a power evaluation similar of one of the generators which would supply a power network. Circuit breakers perform an imperative role in protecting exclusive equipment from damage through faults to prevent expensive failures and problems that could even concession the safety of the substation.
