    Abstract: As a pressure relief and explosion prevention device of oil-immersed power transformer, the pressure relief valve is one of the key equipment in non-electric protection system. This paper sorted out the test classification of pressure relief valve device and analyzed its key performance parameters, the specific reasons and difficulties were analyzed for the problems existing in the test, such as the hysteresis of test standard, the complex testing equipment without unified technical specifications, the high unqualified rate of routine tests, the difficult implementation of the open time test, and the imperfect displacement performance test. Finally, this paper put forward the corresponding measures and rationalization suggestions.
    Key words: transformer; pressure relief valve; performance test; operating pressure; open time
