根據國際(ji)電(dian)(dian)(dian)工委員(yuan)會(IEC)61934標準，局(ju)(ju)部放電(dian)(dian)(dian)是“*部分橋接導體(ti)之間絕(jue)(jue)(jue)緣的局(ju)(ju)部放電(dian)(dian)(dian)”。PD是絕(jue)(jue)(jue)緣內部（內部PD）或絕(jue)(jue)(jue)緣表(biao)(biao)面（表(biao)(biao)面PD）局(ju)(ju)部電(dian)(dian)(dian)應(ying)力集(ji)中的結(jie)果(guo)。當(dang)局(ju)(ju)部電(dian)(dian)(dian)場(chang)應(ying)力足以電(dian)(dian)(dian)離繞(rao)組表(biao)(biao)面附近(jin)的空氣時，就會發生表(biao)(biao)面PD。表(biao)(biao)面PD通常很(hen)容易在(zai)視覺上檢測到(dao)(dao)，因為它會釋放紫外線(xian)(UV)，有時還(huan)會看到(dao)(dao)微小(xiao)的火花。由于(yu)局(ju)(ju)部放電(dian)(dian)(dian)，絕(jue)(jue)(jue)緣表(biao)(biao)面有時也會出現白色或黑色粉末。內部 PD 可能(neng)發生在(zai)任何(he)用于(yu)承受高(gao)電(dian)(dian)(dian)場(chang)的旋轉電(dian)(dian)(dian)機的絕(jue)(jue)(jue)緣介(jie)質中。它始于(yu)固體(ti)電(dian)(dian)(dian)介(jie)質內的微觀空隙、裂縫或夾(jia)雜物，固體(ti)或液體(ti)電(dian)(dian)(dian)介(jie)質內的界(jie)面或不同絕(jue)(jue)(jue)緣材料邊(bian)界(jie)處的分層。GZPD-234系(xi)列(lie)便攜式(shi)局(ju)(ju)部放電(dian)(dian)(dian)監(jian)測與診斷系(xi)統圖譜(pu)篩選。線(xian)纜(lan)局(ju)(ju)部放電(dian)(dian)(dian)在(zai)線(xian)監(jian)測主界(jie)面
