使用原則：電流互感器的接線應遵守串聯原則[8]：即一次繞阻應與被測電路串聯，而二次繞阻則與所有儀表負載電流互感器串聯2）按被測電流大小，選擇合適的變比，否則誤差將增大。同時，二次側一端必須接地，以防絕緣一旦損壞時，一次側高壓竄入二次低壓側，造成人身和設備***3）二次側***不允許開路，因一旦開路，一次側電流I1全部成為磁化電流，引起φm和E2驟增，造成鐵心過度飽和磁化，發(fā)熱嚴重乃至燒毀線圈；同時，磁路過度飽和磁化后，使誤差增大。電流互感器在正常工作時，二次側與測量儀表和繼電器等電流線圈串聯使用，測量儀表和繼電器等電流線圈阻抗很小，二次側近似于短路。CT二次電流的大小由一次電流決定，二次電流產生的磁勢，是平衡一次電流的磁勢的。若突然使其開路，則勵磁電動勢由數值很小的值驟變?yōu)楹艽蟮闹?，鐵芯中的磁通呈現嚴重飽和的平頂波，因此二次側繞組將在磁通過零時感應出很高的尖頂波，其值可達到數千甚至上萬伏，危及工作人員的安全及儀表的絕緣性能。另外，二次側開路使二次側電壓達幾百伏，一旦觸及將造成觸電***。因此，電流互感器二次側都備有短路開關，防止二次側開路。在使用過程中，二次側一旦開路應馬上撤掉電路負載，然后。
