Deterioration Pattern Analysis and Surface Leakage Current of Electrical Insulation in External Pollution

외부 오염 환경하에서 고분자 절연재료의 표면 누설전류 측정 및 열화 패턴 분석

In this paper, the polymer insulators which had been used for electrical insulation were investigated surface leakage current and deterioration pattern. Because the electrical fault took place at the dust occurrence area due to environmental pollution. In particular, the dust accumulates easily on insulation material which is exposed an external long time. The leakage current brings out electrical fault after all. Also, it is need to variation of material and shape to repress a leakage current on electrical material. In this paper, we measured a leakage current on electrical material of facilities by dust, and in experiments the prevention to electrical fault was studied.
