产品概述
绝缘材料低压漏电起痕试验仪概述：
耐漏电起痕试验（电痕化指数试验）是根据 UL746A 、IEC60112 、IEC60335、IEC884-1、 GB2099.1、GB/T4207、GB4706.1 ASTMD 3638-92 等标准规定的模拟仿真试验项目。耐漏电起痕试验（电痕化指数试验）是在固体绝缘材料表面上，在规定尺寸 ( 2mm × 5mm ) 的铂电极之间，施加某一电压并定时 (30s) 定高度 ( 35mm ) 滴下规定液滴体积的导电液体 (0.1%NH4CL) ，用以评价固体绝缘材料表面在电场和潮湿或污染介质联合作用下的耐漏电性能，测定其相比电痕化指数 (CTI) 和耐电痕化指数(PTI) 。电痕化是指固体绝缘材料在电应力和电解杂质的联合作用下，在表面（或内部）产生导电通道。
