A general computer program using the phase co-ordinate technique has been developed for analysing series, shunt and simultaneous faults on balanced and unbalanced polyphase electrical networks. The program eliminates the need for maintaining numerous fault analysing subroutines, one for each kind of fault, and makes the solution of many difficult and previously unsolvable problems possible. It is employed to analyse the cross-country fault involving different phases. The solution method, program outlines and postfault results of voltages, currents and apparent power of an actual power system are given.
