交(jiao)流電(dian)(dian)(dian)源所(suo)能提(ti)供的總功(gong)(gong)(gong)(gong)(gong)(gong)率(lv)，稱之為“視在(zai)(zai)功(gong)(gong)(gong)(gong)(gong)(gong)率(lv)”或“表現功(gong)(gong)(gong)(gong)(gong)(gong)率(lv)”，在(zai)(zai)數(shu)值上是交(jiao)流電(dian)(dian)(dian)路(lu)中電(dian)(dian)(dian)壓與電(dian)(dian)(dian)流的乘積。視在(zai)(zai)功(gong)(gong)(gong)(gong)(gong)(gong)率(lv)用字母S表示(shi)，即S=U×I，單位是伏安(an)（VA）或千伏安(an)（KVA）。它(ta)通常(chang)用來表示(shi)交(jiao)流電(dian)(dian)(dian)源設備（如變壓器）的容量(liang)大小。視在(zai)(zai)功(gong)(gong)(gong)(gong)(gong)(gong)率(lv)既(ji)不等(deng)(deng)于(yu)有(you)功(gong)(gong)(gong)(gong)(gong)(gong)功(gong)(gong)(gong)(gong)(gong)(gong)率(lv)，也不等(deng)(deng)于(yu)無功(gong)(gong)(gong)(gong)(gong)(gong)功(gong)(gong)(gong)(gong)(gong)(gong)率(lv)，但它(ta)既(ji)包(bao)(bao)含有(you)功(gong)(gong)(gong)(gong)(gong)(gong)功(gong)(gong)(gong)(gong)(gong)(gong)率(lv)又包(bao)(bao)含無功(gong)(gong)(gong)(gong)(gong)(gong)功(gong)(gong)(gong)(gong)(gong)(gong)率(lv)。能否(fou)使視在(zai)(zai)功(gong)(gong)(gong)(gong)(gong)(gong)率(lv)為800KVA的變壓器輸出800KW的有(you)功(gong)(gong)(gong)(gong)(gong)(gong)功(gong)(gong)(gong)(gong)(gong)(gong)率(lv)，主(zhu)要取決于(yu)負載(zai)的功(gong)(gong)(gong)(gong)(gong)(gong)率(lv)因數(shu)。

配電(dian)線路(lu)(lu)補(bu)(bu)償(chang)(chang)：線路(lu)(lu)無功(gong)補(bu)(bu)償(chang)(chang)即通過在線路(lu)(lu)桿(gan)塔上安裝電(dian)容(rong)器(qi)實現(xian)(xian)無功(gong)補(bu)(bu)償(chang)(chang)。線路(lu)(lu)補(bu)(bu)償(chang)(chang)點(dian)不(bu)宜(yi)過多;控制方(fang)式(shi)應(ying)從簡，一般(ban)不(bu)采(cai)用分組投(tou)(tou)切控制;補(bu)(bu)償(chang)(chang)容(rong)量(liang)也不(bu)宜(yi)過大，避(bi)免出現(xian)(xian)過補(bu)(bu)償(chang)(chang)現(xian)(xian)象;保(bao)護(hu)也要從簡，可采(cai)用熔(rong)斷器(qi)和避(bi)雷(lei)器(qi)作為過流(liu)和過壓保(bao)護(hu)。線路(lu)(lu)補(bu)(bu)償(chang)(chang)方(fang)式(shi)主(zhu)要提供線路(lu)(lu)和公用變壓器(qi)需要的無功(gong)，該種方(fang)式(shi)具有投(tou)(tou)資小、回收快(kuai)、便于管理和維護(hu)等(deng)優(you)點(dian)，適用于功(gong)率因數(shu)低、負(fu)荷重的長線路(lu)(lu)。缺點(dian)是存在適應(ying)能力差，重載(zai)情況下補(bu)(bu)償(chang)(chang)不(bu)足(zu)等(deng)問題。
