The Properties of Leakage Current of Silicone Rubber wish the Recovery of Hydrophobicity

발수성 회복에 따른 실리콘 고무의 누설전류 특성

The polymer insulators which are installed on outdoor have a great advantage than porcelain and 71ass, due to suppression of leakage current, light weight, low cost, etc. It needs variable evaluation methods for application of these insulators on service. The analysis of measuring leakage current is useful for ageing diagnosis because of monitoring in real-time. In this paper, we look over the recovery of hydrophobicity of silicone rubber in mini salt-fog chamber with leakage current monitoring. also, we understand the relation of between hydrophobicity and leakage current and discuss on method of leakage current monitoring.
