【Abstract】 Based on a large number of tests,the inception corona voltage and corona possibility under different humidity and ESDD are obtained. The results show that the inception corona voltage is content to a statistical rule. Through curve fitting, the equation between inception corona voltage and humidity and ESDD is found,which will be instructive to diagnosis on line on zero insulators.更多还原
