The present invention relates to the analysis of current sensor signals of a multi-phase electrical system. According to the invention, signal paths between a current sensor element and a measuring device are coupled to a predetermined electric potential for a short time. A change in the subsequent measurement results can then be analyzed to see if they are indicative of a possible malfunction during the measurement. 本发明涉及对多相电气系统的电流传感器信号的检验。对此，电流传感器元件和测量装置之间的信号路径短暂地与预先给定的电位耦合。于是可以分析下游的测量值检测中的改变，以便推断出检测期间的可能的功能故障。
