Abstract

Increasing resistive leakage current is high responsible to the degradation of zinc oxide surge arrester. This current is temperature dependence which means the leakage current increase while the temperature of the zinc oxide increased. The resistive leakage current is part of the total leakage of ZnO arrester, means that total leakage current consist of resistive leakage current and capacitive leakage current. This current can obtain from the total leakage current of zinc oxide arrester by subtracting the capacitive current from the total leakage current. Currently, the most methods to separate the resistive leakage current require voltage measurement. Although, the result are satisfactions but still complicated and expensive caused by high voltage measurement needed. This paper develops a simple but accurate method to separating the resistive leakage current from the total leakage current. In this method did not require the voltage measurement so make it cheap to apply in device. The method based on the cancellation of capacitive leakage current from the total leakage current. To obtain capacitive leakage current some steps should be done and the results meet satisfaction.
