Abstract:
High Voltage insulators are vital components in
transmission and distribution systems in a power network.
Most of the insulators are used in open air applications where
they are subjected to different environmental conditions.
Exposure to these different weather conditions and
contaminations determine their performance as insulators.
Condition monitoring of power line insulators is an important
requirement for asset management and engineers in a power
network in order to maintain a healthy power system. There
are several techniques that have been introduced to fulfill this
requirement. One of the techniques of measuring surface
leakage current is introduced here. In this paper, rainy
weather conditions are simulated in an artificial rain making
chamber and the performance of insulators are examined at
different contamination levels. This paper highlights the
concepts of measuring surface leakage current for insulators
under contaminated conditions. Results show that the surface
leakage current is closely related to the insulator condition.
