In a 132 kV, 3-phase, 50 Hz power system, the line to ground capacitance is 0.03 μF and the inductance is 6H. Calculate the following: (1) Voltage appearing across the breaker pole when a magnetizing current of 7 A (Instantaneous value) is interrupted. (2) Resistance to be connected across the contacts to eliminate the restriking voltage.
