Abstract
Electric isolation test is the essential part in equipment qualification. But the lack of electric isolation test standard causes the large diversity in the equipment qualification test. Firstly, this paper analyzes the principle of isolation design of electrical equipment, and then puts forward a set of test requirements, specifies the test level of isolation test to verify whether the electric isolation design can achieve the engineering application. After analyzing the interface character of isolation electrical equipment, combined with the isolation test experience of global DCS platforms in isolation qualification test, this paper gives a whole test method. This method was well practiced in equipment qualification of proprietary intellectual property rights nuclear safety digital I&C platform in China, obtaining good results.
