Abstract

Insulator leakage current can effectively predict the degree of its contamination

the possibility of the occurrence of pollution flashover

icing flashover and the level of aging of insulation materials. The extraction and selection of leakage current characteristic has a prominent influence on the accuracy of the monitoring of the external insulation condition and material aging level. The leakage current characteristics extractions have been conducted extensively and a systematic summarization is in urgent necessary. In this paper

the applications of leakage current characteristics are reviewed in a systematic way

including the forecasting of the insulators contamination degree

the pollution and icing flashover and the monitoring of insulations aging level. The leakage current characteristics are classified into 3 categories: the amplitude characteristics

the waveform and harmonic characteristics and the other characteristics. Finally

the research progressing of each individual characteristic is systematically introduced and analyzed

and a preliminary forecast in this field is given. This paper can be taken as a good reference for the further study of insulator leakage current.
