描述

測量電機絕緣主要分兩種，一種是繞組對地絕緣，還有就是繞組相間絕緣。都是使用兆歐表（搖表）測量。

另外繞組層間（匝間）絕緣也是一種，但要使用萬用表測量。

測量繞組對地絕緣時，要把電機的接線全都拆掉。先檢查搖表的好壞，做開路、短路試驗。搖表沒問題后，用搖表一個表筆接電機外殼，轉(zhuǎn)動搖把，達到120轉(zhuǎn)/分，此時另一個表筆接繞組的一端，當(dāng)讀數(shù)穩(wěn)定時，就是這個繞組的對地絕緣阻值。三個繞組要分別測量三次，有的電機是已經(jīng)把星型連接接好了的，只引出三根出線，那就只需搖測一次就行。

相間絕緣就是繞組之間的絕緣，把表筆先接在一個繞組上，然后轉(zhuǎn)表、測量另一個繞組與它的阻值。最低要求是每伏一K，即；1K/V380V的電機是380K。一般要大于0.5兆。

層間絕緣使用萬用表測量，就是通過比較三個繞組的直流電阻值來判斷繞組是否存在層間（匝間）短路的故障。當(dāng)測量后有一組數(shù)值明顯偏小時，就懷疑這組層間有問題了。
