Paper Title:
Measurement and Analysis of the Leakage Current on the Surface of Polluted Suspension Ceramic Insulator
  Abstract

The artificial pollution tests are implemented on an IEC standard suspension insulator, and the leakage current waveforms and frequency characteristics were investigated under different equivalent salt deposit density ESDD and relative humidity. It was found that the peak values of the leakage current, the total harmonic distortion (THD) and the odd order harmonic components, e.g. 150 and 650Hz, were significantly correlated with the contamination condition of the insulator surfaces. Besides, a new characteristic parameter IMR,defined as the product of the peak values of leakage current by the ratio of the 3rd order harmonic components to the 13th order harmonic components, is introduced to evaluate the contamination condition on the insulator surface.
