| Abstract: | Based on the expounding of leakage current monitoring principle, design and realization of a kind of on-line contamination leakage current monitoring system for transmission lines are introduced. This system measures the data of the leakage current on surface of the insulator and temperature as well as humidity of environment online through the data acquisition unit based on the theory of the adaptive noise cancellation. The data is then transmitted to the supervision system by wireless communication, and analyzed by the expert system. When the contamination degree of insulator is serious, the system will issue alarm signal in time. It provides scientific foundations for plotting contamination zone correctly and realizing condition maintenances. |
