Abstract This paper introduces the reformation scheme of 6kV auxiliary power system using cable interconnection. After the reformation, successfully using one auxiliary transformer loading two auxiliary power system to startup or shutdown unit, which greatly reduces the power consumption of stand-by transformer, and the economic benefits are obvious.
