Article Preview

Abstract:

In order to switch line protection to bus coupler protection when bus coupler circuit breaker is in place of by pass state for line bay efficially and reliable, according to experience of Chinese substation building. this paper presents 3 switch modes. At last, reference with the habits of Zambia , this paper presentsone better mode for Zambia substation through comparing the effectiveness and reliability of the 3 switchmodes.
