摘　　要：灰关联分析了现场220 KV绝缘子在线监测的大量实时数据及相对湿、温度和温度变化率对绝缘子泄漏电流I的影响程度。结果表明相对湿度影响最大,关联度>0.9。通过研究可初步确定温、湿度气象因素对I影响的权重,以供研究绝缘子泄漏电流与其表面污秽状况的对应关系参考。Based on the grey theory, the grey relational analysis is used to realize the fault analysis by the data of the temperature humidity and leakage current from on-line monitoring of 220 kV insulators. The result of the analysis shows that the leakage current of insulators on HV lines is affected by all of the meteorological conditions. And the humidity is decisive factor among them. The degree of relation between the leakage current and the humidity is above 0. 9. In the subsequent working, this conclusion provides foundation to set the weight of each element in the prediction to the contamination of the isolators on HV lines.
