【 摘 要 】

This paper gives an analysis and investigation for the existing problems of traditional on-line monitoring devices of transformer core earthing under low temperature condition, such as poor reliability, high failure rate etc. Then design and develop a new on-line monitoring devices of transformer core earthing current for cold climate, and it has been on-line operated in Mohe Country Xilinji 66kV substation of Heilongjiang Province.
