Summary: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.
