This paper elaborates theoretically the corona current characteristics of insulator strings under high voltage application and verifies them by experiment. It shows that the corona currents of insulator strings are of statistic characteristic and related with the parameters such as the applied voltage
the degree of its surface filth and the environmental humidity. A conclusion is obtained that the corona current method is practical to on-line monitor the insulating condition of insulator strings.
