Abstract: Aiming at the phenomenon of the capacitor voltage protection misoperation or refusing action in the transformer substation construction acceptance and check maintenance because of the voltage protection secondary wiring errors, this paper developed a set of secondary wiring verifier based on the secondary wiring principle and testing method for the differential pressure or voltage imbalance protection, to replace the traditional secondary circuit core wire verification method. This paper expounded the software and hardware design flow of verifier systematic framework. The practical application shows that this verifier is simple to be used and the test results are accurate and effective with shortening testing time.
Key words: capacitor; voltage protection; verifier
