| Abstract: | Tis paper proposes a mathematical model suited to figure out short-circuit current through a zero impedance branch. The model uses a zero impedance branch to simulate switch-equipment, such as breaker, etc, and the symmetrical component analytical method basic principle is applied to calculate short-circuit current through switch-equipment when short-circuit happenes at either side of switch-equipment. It can be used in every kind of operational method. The validity of the model with an instance is proved. |
