對(duì)于電流互感器退磁，一次繞組開(kāi)路，二次繞組通以工頻電流，從零開(kāi)始逐漸增加到一定的電流值(該電流值與互感器的設(shè)計(jì)測(cè)量上限有關(guān)，一般為額定電流的20-50%左右。可以電流互感器這樣判斷，如果電流突然急劇變大，此時(shí)表示鐵芯以進(jìn)入磁飽和階段)。然后再將電流緩慢降為零，如此重復(fù)2-3次。在斷開(kāi)電源前，應(yīng)將一次繞組短接，才斷開(kāi)電源。鐵芯退磁完成。此方法稱(chēng)開(kāi)路退磁法。對(duì)于有些電流互感器，由于二次繞組的匝數(shù)都比較多。若采用開(kāi)路退磁法，開(kāi)路的繞組可能產(chǎn)生高電壓。因此可以在二次繞組接上較大的電阻(額定阻抗的10-20倍)。一次繞組通以電流，從零漸變到互感器一次繞組的允許的額定電流，再漸變到零，如此重復(fù)2-3次。由于接有負(fù)載鐵芯可能不能完全退磁。由于一次繞組的額定電流有限制，過(guò)大的話(huà)可能燒壞一次繞組。如果接有負(fù)載的二次繞組產(chǎn)生電壓不是過(guò)高的話(huà)，可以加大二次繞組的負(fù)載電阻。這樣可以提高退磁效果。準(zhǔn)確度檢查互感器誤差試驗(yàn)一般采用被測(cè)互感器與標(biāo)準(zhǔn)互感器進(jìn)行比較，兩互感器的二次電流差即為被測(cè)互感器誤差。此種檢驗(yàn)方法稱(chēng)比較法。標(biāo)準(zhǔn)互感器要求比被測(cè)互感器高出二個(gè)等級(jí)，此時(shí)標(biāo)準(zhǔn)互感器誤差可忽略不計(jì)。上海喆和定制銷(xiāo)售西門(mén)子APT（原上海二工）ALH-0.66
