Abstract：The main transformer gas protection is a main protection for oil immersed transformer, its proper motion is very important for the operation of the transformer. In this paper, by analysis of a transformer heavy gas protection action accident, we find the reason about the fault, and how to preventing the gas relay malfunction.
