摘　　要：为了选取合理的电气设备监测和诊断参量,将灰关联分析应用于参量的分析中.先确定参考序列和比较序列,计算关联度,然后确定合理的参量.并以氧化锌避雷器(MOA)的绝缘诊断为实例,经计算比较表明,采用阻性泄漏电流基波峰值作为参量来监测和诊断MOA的绝缘状态是合理的.To select the reasonable parameter of condition monitoring and fault diagnosis for electrical equipments, the grey relational analysis was used in the parameter＇s analyzing. The referenced and comparative sequences are confirmed firstly, then the grey relational degree was calculated and reasonable parameter confirmed. Finally, the value of fundamental frequency resistive leakage peak current of MOA is proved to be reasonable by an example.
