對于沒有采取補償措施的電流互感器，比差為負值，角差為正值，比差的***值和角差均隨電流增大而減小。采用補償?shù)霓k法可以減小互感器的誤差。一般通過在互感器上加繞附加繞組或增添附加鐵心，以及接入相應(yīng)的電阻、電感、電容元件來補償。常用的補償法有匝數(shù)補償、分數(shù)匝補償、小鐵心補償、并聯(lián)電容補償?shù)?。校驗方法在進行電流互感器誤差試驗之前，通常需要檢查極性和退磁等試驗。極性檢查電流互感器一次繞組標志為P1、P2，二次繞組標志為S1、S2。若P1、S1是同名端，則這種標志叫減極性。一次電流從P1進，二次電流從S1出。極性檢查很簡單，除了可以在互感器校驗儀上進行檢查外，還可以使用直流檢查法。退磁檢查電流互感器在電流突然下降的情況下，互感器鐵芯可能產(chǎn)生剩磁。如電流互感器在大電流情況下突然切斷電源、二次繞組突然開路等?；ジ衅麒F芯有剩磁，使鐵芯磁導(dǎo)率下降，影響互感器性能。長期使用后的互感器都應(yīng)該退磁。互感器檢驗前也要退磁。退磁就是通過一次或二次繞組以交變的勵磁電流，給鐵芯以交變的磁場。從0開始逐漸加大交變的磁場(勵磁電流)使鐵芯達到飽和狀態(tài)，然后再慢慢減小勵磁電流到零，以消除剩磁。上海電流互感器貨源充足</p><p
