If the source impedance at a 13.2 kV distribution substation bus is (0.5+ jl.5) N per phase, compute the RMS and maximum peak instantaneous value of the fault current, for a balanced three-phase fault. For the system (X/R) ratio of 3.0, the asymmetrical factor is 1.9495 and the time of peak is 7.1 ms withstanding peak current capability to which all substation electrical equipment need to be designed. .
