【Abstract】 The transient process of the voltage transformer charge flow and the factors caused overcurrent are analyzed by the instantaneous symmetric component method after single-phase ground fault disappears. A single-phase ground fault model of 10 kV distribution network system is anslysed based on the ATP-EMTP electromagnetic transient simulation software, and the corresponding suppression measures are put forward.更多还原
