Abstract

We investigate surface leakage current on porcelain insulators under dry weather conditions. Clean and polluted insulators are compared. And the relationship between their surface leakage current and weather conditions is studied. As a result, the polluted insulator gives a larger leakage current than the clean insulator. Also, it is shown that the leakage current of the clean insulator is strongly dependent on the absolute humidity.

干燥条件下洁净绝缘子与污染绝缘子表面泄漏电流的比较
我们研究了干燥天气条件下瓷绝缘子的表面漏电流。对清洁绝缘子和污染绝缘子进行了比较。研究了其表面泄漏电流与天气条件的关系。因此,被污染的绝缘子比干净的绝缘子产生更大的泄漏电流。此外,洁净绝缘子的泄漏电流与绝对湿度有很大的关系。
