Abstract
This paper presents measurements of low-level leakage current (LC) patterns on naturally aged insulators and artificially contaminated material sample s as well as insulators. A nonlinear behavior of the LC has been observed. Possible causes for this behavior are discussed and its relations to surfac e hydrophobicity and electric stress are described. In addition, neural net works are trained to recognize the LC patterns as well as to estimate their harmonic contents.
