Abstract

Abstract

The working principle and determining method of action resistance value of leakage protection of 3.3 kV movable substation were introduced in this paper. The system’s hardware circuit of 3.3 kV leakage protection was given and the simulation test was carried out under artificial condition. The simulation test showed that the technical scheme is feasible, parameters are reasonable and the tripping is reliable and sensitive.
