| Abstract: | When the isolators of No.2 transformer 220kV bus-bar I was changed in a 220kV substation, the protection of 220kV transmit the "bus-bar voltage failure" signal during the impulse test. Through analyzing the protections circuit, this paper reveals that the course of the accident is the defect in secondary voltage circuit. Some preventive treatments are also proposed in operation |
