漏電起痕試驗(yàn)是在固體緣材料表面上,在規(guī)定尺寸(2mm×5mm )的鉑電之間,施加某一電壓并定時(shí)(30s)定高度(35mm)滴下規(guī)定液滴體積的污染液體(0.1%NH 4 CL),用以評(píng)價(jià)固體緣材料表面在電場(chǎng)和污染介質(zhì)聯(lián)合作用下的耐受能力,測(cè)定其相比電痕化指數(shù)(1)和耐電痕化指數(shù)(PT1)。Tracking test in solid insulating materials on the surface, in terms of size ( 2mm ×5mm ) between platinum elerodes, applying a voltage and timing ( 30s ) constant height (35mm ) drops under the droplet size of the contaminated liquid ( 0.1%NH 4 CL ), to evaluate the surface of the solid insulating material in eleric and the contaminated medium under the aion of combined determination of tolerance, comparing the tracking index ( 1 ) and resistance to tracking index ( PT1 ). Applied to IEC60112:2009
