摘要


Every year, the power grid accident caused by GIS fault has caused serious losses to the national economy. The full circuit resistance test of GIS equipment under power outage can timely and effectively find the defects such as loose node, poor contact or joint surface oxidation caused by long-term non-operation of the bus and each branch.
