本文件描述了固體絕緣材料耐電痕化和相比電痕化指數(shù)的測量方法,適用于交流電壓下使用的設(shè)備元件和盤狀材料。 本文件提供了按照要求測定電蝕損的程序。 注1:耐電痕化指數(shù)的測量可作為材料的驗收標準,也可作為對材料及零部件進行質(zhì)量控制的方法。 相比電痕化指數(shù)主要可用作材料的基本特性表征和性能比較的參數(shù)。 本文

Method for the determination of the proof and the comparative tracking indices of solid insulating materials
本試驗方法可測量在電壓最高達600V時固體電氣絕緣材料在電場作用下表面暴露于含雜質(zhì)的水時的相對耐電痕化性能。 當將電壓施加到放在材料表面上規(guī)定的電極裝置之間，且電解液以規(guī)定的時間間隔滴到兩電極之間時，在此試驗情況下可能產(chǎn)生電痕化。引起材料破壞所必需的液滴數(shù)隨著施加電壓的減少而增加
