 Title: Transmission Line Analysis of Polluted Insulator Leakage Current
ABSTRACT
 Contamination of high-voltage overhead transmission line insulators to conduct research and analysis conditions are given high-voltage transmission line insulator contamination leakage current analysis system principles and technical indicators and on-site monitoring of case analysis; summarized in April 2009 to 12 months, the real-time monitoring The insulator surface leakage current with the changing circumstances of climate change; raising the level of determining the accuracy of insulator contamination monitoring results of the analysis for insulator state detection and the "time" to make an effective technical support for cleaning.
