Question 1) a) Calculate the short-circuit ratio at the point of common coupling (PCC) of an industrial network, while the three-phase short- circuit capacity and line-to-line voltage at the PCC are 18 MVA and 12 KV, respectively. Also, the average load demand for a week is 82 KW, and the average billed power factor is 0.94. b) If the total demand distortion (TDD) value with respect to the following current waveform in a load is 18%, then find out the value of P. Consider the average maximum rms load demand at the fundamental frequency component for a week is 80 amp. i(t)=P+80cosot Question 1) a) Calculate the short-circuit ratio at the point of common coupling (PCC) of an industrial network, while the three-phase short- circuit capacity and line-to-line voltage at the PCC are 18 MVA and 12 KV, respectively.
