Solution of network transients using symmetrical-component techniques

The paper shows how, without any loss in generality, symmetrical-component techniques can be used to analyse power-system fault transients in static networks. The general theory is developed and formulas are given for evaluating the phase-current transients in simple and sequential shunt faults. In the case of the phase-to-phase fault developing into a 3-phase fault, it is shown that more than current doubling is possible.
