Abstract
A device and a method for detecting a state of an electrical device. A magnetic field is thereby measured by a magnetic field sensor along an electrical power supply cable of the electrical device via which the electrical device is supplied with power; a magnetic field is thereby measured by a magnetic field sensor, and the magnetic field measured in this manner is compared with previously determined reference values in order to determine the operating state of the electrical device. The process of determining the reference values may thereby be individually adapted in an upstream calibration process to the electrical device to be monitored.
