Abstract:
For technically adequate interruptive performance, circuit breaker (CB) must be able to sufficiently interrupt current and voltage transients in power system network. Transient recovery voltage (TRV), an overvoltage transient resulting from the initiation, or interruption of current greatly affects breaking capacity of breakers. This work investigates TRV across circuit breaker and presents an effective method of limiting it. EMTP-ATP software was used to create the model and simulation.
