Electrical and Electronics Engineering : In a 132kV circuit breaker the bushing to ground capacitance is 0.01 microFarad and the transformer inductance succeeding the circuit-breaker is 4H. What will be the voltage appearing across the poles of circuit-breaker as it breaks a magnetising current of 15A flowing in the transformer?
