1、測(ce)量(liang)前后對(dui)電容器兩(liang)及(ji)之(zhi)間，兩(liang)及(ji)與地(di)之(zhi)間，均應(ying)充分(fen)放(fang)電，尤(you)其對(dui)電力(li)電容器應(ying)直接從兩(liang)個引出端上(shang)直接放(fang)電，而(er)不應(ying)僅在連(lian)(lian)接導(dao)線板上(shang)放(fang)電，因為大多(duo)數電力(li)電容器兩(liang)及(ji)與連(lian)(lian)接導(dao)線板連(lian)(lian)接時均串有(you)熔(rong)斷(duan)器，若某電力(li)電容器熔(rong)斷(duan)器熔(rong)斷(duan)，在連(lian)(lian)接板上(shang)放(fang)電不一定能將該

2、應按大容量試品的絕(jue)(jue)緣(yuan)(yuan)電(dian)阻測(ce)量方(fang)法搖(yao)測(ce)電(dian)容器。在搖(yao)測(ce)過程中(zhong)應在未斷(duan)開絕(jue)(jue)緣(yuan)(yuan)兆歐表(biao)以前，不停止(zhi)搖(yao)測(ce)手柄，防止(zhi)反充電(dian)損壞兆歐表(biao)。

3、不允(yun)許(xu)長時間(jian)(jian)(jian)搖(yao)(yao)測電(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)容(rong)(rong)(rong)器(qi)兩(liang)(liang)(liang)及(ji)(ji)(ji)(ji)之間(jian)(jian)(jian)的(de)絕(jue)緣(yuan)電(dian)(dian)(dian)(dian)阻。因電(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)容(rong)(rong)(rong)器(qi)電(dian)(dian)(dian)(dian)容(rong)(rong)(rong)量較(jiao)大(da)，儲存電(dian)(dian)(dian)(dian)荷(he)也多，長時間(jian)(jian)(jian)搖(yao)(yao)測時若操作不慎易造成人身(shen)及(ji)(ji)(ji)(ji)設備事故。有些單位在搖(yao)(yao)測電(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)容(rong)(rong)(rong)器(qi)兩(liang)(liang)(liang)及(ji)(ji)(ji)(ji)絕(jue)緣(yuan)狀況(kuang)時，一(yi)般先將兆歐(ou)表輕搖(yao)(yao)幾轉(zhuan)，一(yi)般不超過5轉(zhuan)，然后(hou)通(tong)過電(dian)(dian)(dian)(dian)容(rong)(rong)(rong)器(qi)兩(liang)(liang)(liang)及(ji)(ji)(ji)(ji)放(fang)(fang)電(dian)(dian)(dian)(dian)的(de)放(fang)(fang)電(dian)(dian)(dian)(dian)聲及(ji)(ji)(ji)(ji)放(fang)(fang)電(dian)(dian)(dian)(dian)火花(hua)來(lai)判斷絕(jue)緣(yuan)狀況(kuang)。若有清脆的(de)放(fang)(fang)電(dian)(dian)(dian)(dian)聲及(ji)(ji)(ji)(ji)明顯的(de)放(fang)(fang)電(dian)(dian)(dian)(dian)火花(hua)，則認為電(dian)(dian)(dian)(dian)容(rong)(rong)(rong)器(qi)兩(liang)(liang)(liang)及(ji)(ji)(ji)(ji)絕(jue)緣(yuan)狀況(kuang)良好，若無放(fang)(fang)電(dian)(dian)(dian)(dian)聲及(ji)(ji)(ji)(ji)火花(hua)，則可能(neng)是電(dian)(dian)(dian)(dian)容(rong)(rong)(rong)器(qi)內部絕(jue)緣(yuan)受(shou)潮老化或兩(liang)(liang)(liang)及(ji)(ji)(ji)(ji)與電(dian)(dian)(dian)(dian)容(rong)(rong)(rong)之間(jian)(jian)(jian)引線(xian)(xian)(xian)斷開。用這種方法時應注意，對(dui)兩(liang)(liang)(liang)及(ji)(ji)(ji)(ji)放(fang)(fang)電(dian)(dian)(dian)(dian)的(de)放(fang)(fang)電(dian)(dian)(dian)(dian)引線(xian)(xian)(xian)兩(liang)(liang)(liang)端應接在短(duan)絕(jue)緣(yuan)棒上，人身(shen)不能(neng)直(zhi)接接觸(chu)放(fang)(fang)電(dian)(dian)(dian)(dian)引線(xian)(xian)(xian)，放(fang)(fang)電(dian)(dian)(dian)(dian)引線(xian)(xian)(xian)應采用裸銅導(dao)線(xian)(xian)(xian)。

4、沖擊合閘收試(shi)驗時，應(ying)測(ce)量(liang)每相電(dian)流。試(shi)驗前應(ying)將(jiang)測(ce)量(liang)電(dian)流互(hu)感(gan)器(qi)TA事先接于測(ce)量(liang)回路中。如電(dian)容(rong)器(qi)組為星形接線，應(ying)將(jiang)測(ce)量(liang)電(dian)流互(hu)感(gan)器(qi)TA串接于電(dian)容(rong)器(qi)中性點側(ce)的回路內；

5、三相電(dian)流不平衡(heng)時，應檢(jian)查(cha)電(dian)容(rong)器(qi)組熔斷(duan)(duan)器(qi)有(you)無熔斷(duan)(duan)，電(dian)容(rong)量是否合適等。檢(jian)查(cha)前(qian)仍應對電(dian)容(rong)器(qi)兩ji直接放電(dian)，防止熔斷(duan)(duan)器(qi)熔斷(duan)(duan)使電(dian)容(rong)器(qi)帶(dai)有(you)殘余電(dian)荷。
