RMS Symmetrical Fault Current
November 8th, 2022
In the attached figure, assume the following values: V = 4kV, X = 3 Ohm, R = Ohm, and w = 2(pi)(60) rad/sec. Calculate the following three currents: the rms symmetrical fault current, the rms asymmetrical fault current at the instant the switch closes (assuming maximum dc offset), and the rms asymmetrical fault current 5 cycles after the switch closes (assuming maximum dc offset).
