Description
−過電流の場合の磁気オフセットの危険性。この過負荷は磁気材料からの残留磁場に因る偶発的飽和を引き起こすことがある。これはセンサーの精度に悪影響を及ぼす。その結果、それは消磁されなければならない。従って、このための頻繁なメンテナンスが必要である。
−通常、センサーは温度変化に対して非常に敏感である。ホール効果セルの電圧Vhに対する磁界Bに関連する計算定数は温度によって変化する。セルもまたオフセット電圧を引き起こして、ゼロ電流の近くで不正確を引き起こす。
−磁心と、

−磁心に巻かれる二次コイルと、
−電気接地と二次コイルの第1端子の間に接続される電子発振器と、
−電気接地と励磁回路を経由して二次コイルの第2端子の間に接続される測定抵抗と、
を備えることを特徴とする。
