What will be an ideal response?
A 1000-MVA 20-kV, 60-Hz three-phase generator is connected through a 1000-MVA 20-kV ?/138-kV Y transformer to a 138-kV circuit breaker and a 138-kV transmission line. The generator reactances are ??=0.15, ? =0.45 and =1.8 pu. The transformer series reactance is 0.1 pu; transformer losses and exciting current are neglected. A 3-phase short-circuit occurs on the line side of the circuit breaker when the generator is operated at rated terminal voltage and at no-load. Determine the substransient current through the breaker in pu and in kA rms ignoring any dc offset.
A. The base current on the high voltage side of the transformer is:
