Being added an anti - phase compensating winding , this device , which is placed between high voltage line and first insulator , makes the synthesized magnetic field in magnetic core reach a dynamic balance , and thus solves the problems from remanence and assures the measurement accuracy 其漏電流傳感器增加一個(gè)反相的補(bǔ)償線圈,使得電流傳感器磁芯內(nèi)的合成磁場(chǎng)達(dá)到動(dòng)態(tài)平衡,解決了由于剩磁而帶來(lái)的問(wèn)題,保證了測(cè)量精度。
