本发明基于用于测量至少一个交流电流的电流测量装置，其具有至少一个感应耦合单元，其旨在将至少一个电主信号转换为至少一个电二次信号，以及计算单元 ，其旨在确定来自次级信号的主信号。 计算单元旨在在确定主信号时考虑次信号的至少一个高次谐波。

The invention relates to a current measuring device for measuring at least an alternating current with at least one inductive coupling unit (12) which is provided to at least one electrical primary signal (14) to convert it into at least one electrical secondary signal (16), and with a computing unit (18 ), which is provided for determination of the primary signal (14) from the secondary signal (16). It is proposed that the arithmetic unit (18) is intended to take into account at least one higher harmonic of the secondary signal (16) in the determination of the primary signal (14).
