電流互感器一次繞組標(biāo)志為P1、P2，二次繞組標(biāo)志為S1、S2。若P1、S1是同名端，則這種標(biāo)志叫減極性。一次電流從P1進(jìn)，二次電流從S1出。極性檢查很簡單，除了可以在互感器校驗(yàn)儀上進(jìn)行檢查外，還可以使用直流檢查法。 </p> <p> 2、電流互感器退磁檢查 </p> <p> 電流互感器在電流突然下降的情況下，上海定制電流互感器規(guī)格尺寸，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，上海定制電流互感器規(guī)格尺寸?；ジ衅麒F芯有剩磁，使鐵芯磁導(dǎo)率下降，影響互感器性能。上海喆和定制銷售西門子APT（原上海二工）ALH-0.66
