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?；ジ衅鳈z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(dá)到飽和狀態(tài)，然后再慢慢減小勵磁電零，以剩磁。對于電流互感器退磁，一次繞組開路，二次繞組通以工頻電流，從零開始逐漸到一定的電流值(該電流值與互感器的設(shè)計測量上限有關(guān)，一般為額定電流的20-50%左右?？梢噪娏骰ジ衅麟娏骰ジ衅鬟@樣判斷，如果電流突然急劇變大。
