Resistance measurement of breaker loop of HGIS

Abstract

Abstract:

Abstract:In recent years, along with enlargement of the power grid scale, many EHV substations were built. Due to the pressures of environment protection and land occupation, a large quantity of gas insulated metalenclosed switchgear (GIS) was widely used in substation construction. The GIS is becoming indispensable equipment for substations. A mistake, which easily occurs in resistance measurement of breaker conducting loop of the hybrid gas insulated switchgear (HGIS), was analyzed, and some correct measurement methods and the matters needing attention in the measurement were summarized. The result in this paper can be used as reference for handling with similar problems.
