It is important to study the air-gap breakdown characteristics between conductor and tower in rainy weather for improving the reliability of high voltage power grid.In this paper
the breakdown characteristics were studied through artificial simulation test
and the relationships among breakdown voltage and some factors
such as rain intensity
rainwater resistivity
and drop direction were investigated
and the corresponding results were obtained.This study would be helpful for design and maintenance of transmission line against rainy weather.
