  • Publication number: 20240319305
    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.

  • Patent number: 11535351
    Abstract: A device (2) for demagnetizing and for measuring the magnetic signature of a stationary hull (4) and for simulating a magnetic field, including a demagnetization coil assembly (8), a magnetic field sensor assembly (10) and a simulation coil assembly (12a, 12b, 12c), which can be positioned next to the hull (4) in a horizontal manner on one side and the cross-sectional areas of the demagnetization coils (8) and of the simulation coils (12a, 12b, 12c) being disposed in the longitudinal direction of the hull (4) with horizontally oriented surface normals. The demagnetization coils (8) produce an alternating magnetic field; the simulation coils (12a, 12b, 12c) produce a stationary simulated magnetic field in all three dimensions.
