| Abstract: | On the basis of analyzing working principle of installing zero-sequence TV on neutral point of 10 kV bus TV, a resolution to abnormal voltage indication due to inappropriate secondary wiring in the wiring mode is proposed and phasor method is used for analysis of voltage indication after TV high-voltage fuse blown. Finally, the function of auxiliary windings triangular opening shorting method is stated, and running conditions of auxiliary windings under abnormal working condition is discussed. |
