Design and construction of a pollution monitor for power line insulators

Abstract

The basics of insulators' pollution processes are first reviewed, including the main physical and chemical factors involved. A novel fibre-optic-based device for measuring leakage and burst current is described, including the mechanical mounting, electronic modules and the corresponding hardware and calibration software of the equipment developed. A comparative analysis of the advantages and disadvantages of the design with similar equipment is presented. Finally, experimental results in a fog chamber are presented. Some statistical analyses, that can be useful in understanding the pollution process in electrical insulators, will be proposed.

“…Polymeric insulators are very much subjected to the environmental pollution caused by the human activities and industrial fumes. Accumulation of pollution on the insulator surfaces tends to absorb moisture and results in conduction of significant leakage current [9,10]. Hence, Pollutants in dry conditions on the surface of the insulators do not have much effect on its electrical properties but in the presence of moisture, soluble pollutants get dissolve with water and form conductive path over the surface of the insulators which reduces the flash over voltage causing different partial discharge activities [11].…”
