Analysis of Simulatenous Faults by Two-Port Network Theory

Simultaneous faults of common configuration may be described mathematically in terms of two-port network theory with one port for terminating the network at each fault point. Combining the sequence networks, with appropriate phase shifts, will then permit-direct solution of the network voltages and currents in a general way. This approach to solving for simultaneous fault quantities is very orderly and makes solution by hand computation or by computer more straightforward than previous methods.
