Question
04: (A) A 10 MVA, 132 kV transformer is connected to the end of a transmission line of surge
impedance 400Q The transformer has an equivalent capacitance of 0.002 µF and leakage
inductance of 16 H. If a wave of 1000 KV travels through the line and strikes the transformer,
find the surge voltage on the transformer?
(B) A circuit breaker is connected to the high voltage side of a 3-phase, 30 MVA, 132/11 KV,
(Y/Y) transformer. The stray capacitance to ground is 8 nF and the magnetizing inductance is
50 H:
(a) Calculate the voltage appearing across the circuit breaker contacts due to chopping the
magnetizing current of the transformer at one third of its peak value, and (b) What is the
value of a switching resistance required for critical damping of the transient recovery voltage?
