| Abstract: | An accident in the dielectric loss factor and capacitance test across open contacts of 500 kV circuit breaker and in the maintenance is introduced.The causes of the fault are analyzed through electric circuit diagram and the differential equation based on the circuit diagram.It is pointed out that the danger point should be predicted before the dielectric loss factor test,on the grading capacitor which across the circuit breaker open contacts,to prevent potential personal injury. |
