Abstract
A device for checking K phase current sensors for capturing measured values of K corresponding phase currents of an N-phase, electrical load, in particular an electrical machine, with N≥3 and with K<N, is provided. The device is configured to cause the N-phase load to be operated for a test period in a test operating mode in which the sum of the K phase currents, which are captured by the K corresponding phase current sensors, corresponds to a predefined value, in particular zero. Furthermore, the device is configured to determine K measured values from the K corresponding phase current sensors during the test period, and to check at least one of the K phase current sensors on the basis of the K measured values.
