【Abstract】 This paper is focused on the operation of single phase earth protection for little earth current system.Based on the analyses for several kinds of ground protections,one ground protection with the functions of line selection and ground positioning is proposed for the complex automatic and mordern management for the electric substation.By this means,the economic,reliability,safty and stable operation for the grid can be achieved.更多还原
