parallel switching Parallel switching phenomenon when MV/HV circuit breakers interrupt a shared fault current By electrical-engineering-portal.com Published On :: Mon, 07 Jun 2021 06:39:24 +0000 Parallel switching occurs when two or more circuit-breakers are tripped to interrupt a shared fault current. This is typically the case for such bus arrangements as a double breaker, breaker-and-a-half, breaker-and-a-third, and ring buses. Ideally, all of the circuit-breakers should...
