This paper proposes the phase network calculation method- The equivalent impedance of the fault node is computed, then the phase networks of various faults on different phases are deduced- By using the phase network. The calculated results can be obtained through the easy computation and transformation. This new method is superior to the traditional method of the sequence network.
