江西電力補償電容器關鍵的一個階段便是投切，投切方法的挑選十分關鍵，投切方法沒有挑選恰當，形象化的便會造成過補或欠補的難題，高壓電力補償電容器投(tou)切方法挑選沒錯，可是廷時(shi)設定(ding)太高，仍然將會(hui)造(zao)成過補和欠補的難題，廷時(shi)設定(ding)太低(di)，將會(hui)會(hui)經(jing)常投(tou)切造(zao)成電(dian)(dian)力網起伏，毀(hui)壞投(tou)切電(dian)(dian)源(yuan)開關(guan)，減(jian)少電(dian)(dian)力電(dian)(dian)容器使用期。

高壓電力補償電容器決不是無用功率，它的用處很大。電動機需要建立和維持旋轉磁場，使轉子轉動，從而帶動機械運動，電動機的轉子磁場就是靠從電源取得無功功率建立的。電力補償電容器批發變壓(ya)(ya)器(qi)(qi)(qi)也同樣需要無功(gong)(gong)功(gong)(gong)率，才能使變壓(ya)(ya)器(qi)(qi)(qi)的一次線圈產生磁場，在二次線圈感應出(chu)電壓(ya)(ya)。因此(ci)，沒(mei)有無功(gong)(gong)功(gong)(gong)率，電動(dong)機就不(bu)會轉動(dong)，變壓(ya)(ya)器(qi)(qi)(qi)也不(bu)能變壓(ya)(ya)，交流(liu)接(jie)觸(chu)器(qi)(qi)(qi)不(bu)會吸(xi)合。

電力補償電容器全稱無功功率補償，是一種在電力供電系統中起提高電網的功率因數的作用，降低供電變壓器及輸送線路的損耗，提高供電效率，改善供電環境的技術。所以江西電力補償電容器在電(dian)力供電(dian)系(xi)統(tong)中處在一個不可缺少(shao)的非常重要的位(wei)置(zhi)。合理的選(xuan)擇(ze)(ze)無功補償裝置(zhi)，可以(yi)做到最大(da)限度(du)的減(jian)少(shao)電(dian)網的損耗，使電(dian)網質(zhi)量提高。反(fan)之，如選(xuan)擇(ze)(ze)或使用不當，可能造成供電(dian)系(xi)統(tong)，電(dian)壓(ya)波(bo)動，諧(xie)波(bo)增大(da)等諸多因(yin)素。
