A Novel Leakage Current Index for the Field Monitoring of Overhead Insulators Under Harmonic Voltage

Abstract

Leakage current measurement is the most reliable and effective method for condition monitoring of overhead insulators deployed in the field. However, a major challenge in the leakage current based insulator monitoring is to interpret the indices extracted from the leakage current measurements under varying harmonic content in system voltage.
