| Abstract: | Aiming at electromagnetic potential transformer(PT) faults in 35 kV converter station,make discussion, analyzes the causation and influence factor, puts forward reply measures. The analy?sis result shows that the fault is caused by the inside of electromagnetic PT occurring ferro-resonance.Replacing electromagnetic PT by capacitance PT or increasing special anti-resonance device, canavailably avoid this fault to take place. |
