| Abstract;The contamination influences the corona performance of transmission line insulator strings very much. Not only do they change the corona-originated voltage, but also change the quantity and amplitude of the corona pulses. This paper describes the experiment about the corona current at diverse contaminating condition and various voltages. The experimental results show that the corona pulses conform to statistic rule and can be used to distinguish the fault insulators from transmission line insulator strings at the definite environmental condition. And the fuzzy membership function is established according to the results. It can be used as one of the preconditions to detect the fault insulators. (author abst.) |
