Abstract:This paper summarizes some common design problems, installation problems, operational problems, equipment matching problems through many years of electrical systems testing abuout large units, and analyses the regularity. To void this kind of problems, this paper offers a few preventive measures, including according actions and operation orders strictly, modifying some protection fixed value temporary, applying voltage to PT. It can have a reference effect to the electrical systems testing of large units, help to prevent these kind of problems.
