Three-phase current unbalance exists in power system widely.This paper presents an unbalance case of a 220 kV transmission line in a closed 550 kV/220 kV electromagnetic loop,with analyzing its causes and influence factors.Finally,from the aspect of power system operation,this paper summarizes conclusions,which will help provide reference for similar research in the future.
