放下試驗(yàn)端頭，主觸點(diǎn)及常開(kāi)觸點(diǎn)都不應(yīng)導(dǎo)通常閉觸點(diǎn)應(yīng)導(dǎo)通。線(xiàn)圈繞組值就為200毆姆左右。測(cè)量前應(yīng)先把一端的線(xiàn)去掉再測(cè)量。2、用萬(wàn)用表歐姆檔來(lái)測(cè)量常閉輔助觸點(diǎn)通不通。3、用手按主觸頭看器機(jī)構(gòu)卡不卡。4、直接給器線(xiàn)圈通電看看器吸合不吸合！ 2．兩相V形接線(xiàn)該接線(xiàn)方式也稱(chēng)為兩相不完全星形接線(xiàn)。在繼電保護(hù)裝置中稱(chēng)為兩相兩繼電器接線(xiàn)。在中性點(diǎn)不接地的三相三線(xiàn)制電路中，廣泛用于測(cè)量三相電流、電能及作過(guò)電流繼電保護(hù)之用。兩V形接線(xiàn)的公共線(xiàn)上的電流反映的是未接電流互感器那一相的相電流。
