Abstract

It is an efficient method to improve short circuit impedance that autotransformer is grounded by small reactance. In this paper, the restraining method is analyzed. Firstly, base on zero sequence circuit of autotransformer, it was deduced that the equivalent reactance is increased in this method. Then single phase and three phase fault current in 220kV side were calculated after connecting 16 reactance. Earth reactance influence to fault current was analyzed with the above results.
