一、三相電(dian)容電(dian)感測試儀測量電容器

1、測(ce)試電(dian)(dian)(dian)壓電(dian)(dian)(dian)纜(lan)一(yi)端(duan)接到"電(dian)(dian)(dian)壓輸出"25V端(duan)子上，另(ling)一(yi)端(duan)的電(dian)(dian)(dian)纜(lan)夾分別夾在(zai)被測(ce)電(dian)(dian)(dian)容器組(zu)兩極的連接母線(xian)上

2、測試(shi)電流信號(hao)(hao)電纜插(cha)在(zai)"電流輸入"輸入插(cha)頭上，另一端連(lian)于鉗(qian)形(xing)表上,注意鉗(qian)形(xing)表鉗(qian)口方向，電壓(ya)(ya)線紅(hong)夾(jia)子與鉗(qian)形(xing)電流表前面板(有顯示屏)為(wei)同極性，如果接反，測量電壓(ya)(ya)和電流的相角的正負(fu)符號(hao)(hao)錯誤，也不(bu)能正確(que)識(shi)別(bie)電容(rong)或電感試(shi)品;

4、配合使用"↑"、"↓"鍵，屏幕循環顯示:自(zi)(zi)動、電(dian)(dian)(dian)容、電(dian)(dian)(dian)感、電(dian)(dian)(dian)阻，設(she)置試(shi)品(pin)(pin)類(lei)型(xing)(xing)(xing)，通常情況下，采(cai)用默(mo)認方(fang)式:自(zi)(zi)動，儀器會根據測試(shi)電(dian)(dian)(dian)壓和電(dian)(dian)(dian)流的相位差確定試(shi)品(pin)(pin)類(lei)型(xing)(xing)(xing)，有(you)些情況下，因為(wei)(wei)試(shi)品(pin)(pin)電(dian)(dian)(dian)容量(liang)太小(低于儀器測量(liang)下限)，儀器能準確讀(du)出電(dian)(dian)(dian)流有(you)效(xiao)值，但不能測出相角，無法判斷試(shi)品(pin)(pin)類(lei)型(xing)(xing)(xing)，就需要用戶人為(wei)(wei)設(she)定試(shi)品(pin)(pin)類(lei)型(xing)(xing)(xing);

設(she)置好試品類型后，按"→"鍵，光標移動到"電(dian)壓等級"，配合使(shi)用"↑"、"↓"鍵，屏幕循(xun)環顯示:0.38/ kV、6.6kV、6.6/ kV、10kV、10/ kV、11kV、11/ kV、12kV、12/ kV、35kV、35/ kV，選擇電(dian)壓數，是為了計(ji)算電(dian)容(rong)的千(qian)乏(fa)數，不影(ying)響(xiang)電(dian)容(rong)的量值;

設(she)置(zhi)好(hao)合適的(de)電壓(ya)等級，按(an)"→"鍵，光標移(yi)動到"系統(tong)編號"，配合使用(yong)"↑"、"↓"鍵，按(an)位修改好(hao)實際的(de)系統(tong)編號，此作(zuo)用(yong)為了打印和(he)保存(cun)數(shu)據(ju)用(yong);

5、設置好"試品類型"、"電壓(ya)等級"，按"確(que)定(ding)"鍵(jian)，進入(ru)測(ce)試，

儀器實(shi)時采集電(dian)(dian)(dian)壓和電(dian)(dian)(dian)流(liu)信(xin)號，自動計(ji)算(suan)并顯示電(dian)(dian)(dian)壓有(you)(you)效值、電(dian)(dian)(dian)流(liu)有(you)(you)效值、電(dian)(dian)(dian)壓頻率、電(dian)(dian)(dian)壓-電(dian)(dian)(dian)流(liu)的相角(+號為電(dian)(dian)(dian)流(liu)超前電(dian)(dian)(dian)壓，為容性(xing)試品，對應-號為電(dian)(dian)(dian)流(liu)滯(zhi)后電(dian)(dian)(dian)壓，為感性(xing)試品)，儀器經過多(duo)次采集數據后，自動計(ji)算(suan)出結果。

儀器根據電(dian)壓(ya)-電(dian)流(liu)的(de)相角判斷出電(dian)容(rong)型試(shi)品，計算出電(dian)容(rong)量(單位μF)、阻抗(電(dian)容(rong)為容(rong)抗，電(dian)感為感抗)、無功(gong)(gong)功(gong)(gong)率(lv)(單位為kVar，對(dui)應(ying)設(she)置的(de)電(dian)壓(ya)等級);

6、按(an)"打(da)印"鍵，儀(yi)器(qi)打(da)印測試結

二、三相電容電感測試儀測量電抗器或電阻器

儀器自動(dong)識別試品(pin)類型，按類型計算出結果，故測量電抗(kang)器或電阻器的方法同電容器。

注意(yi):測(ce)試(shi)電抗器小于5mH或電阻小于1.25Ω時，電壓(ya)線接入2V電壓(ya)輸出(chu)端子上。
