| Summary: | Leakage current based condition assessment is most extensively opted method to monitor the ageing and deterioration of zinc oxide surge arresters. Particularly, the resistive component of leakage current is considered to be directly related with the arrester's degradation. Therefore, the measurement of resistive leakage current is essential for the condition diagnostic of the surge arrester. Several techniques have been proposed to extract the resistive component of total leakage current. But, the deficiency of a comprehensive review on the existing techniques still exists. This paper is aimed to review the resistive leakage current extraction techniques with respect to their operating principles, experimental procedures, limitations, and accuracy of the results. This study will contribute to improve the accuracy of resistive leakage current based condition monitoring of surge arresters. |
