| Abstract: | Aiming at an inside grounding fault of 750 kV tank breaker, analyzes the action data andwaveshape chart of protection device, finds out fault spot and eliminates the fault. The result shows thatthe cause of fault is the insulated material of pull -stick existing quality problem, inside dischargesunder the steady state voltage, brings about its insulated element breakdown. |
