Abstract
An electromagnetic device comprising a magnetic field-generating electric circuit comprising at least one winding, and a system configured to monitor a condition of the electromagnetic device and/or to control the electromagnetic device. The condition-monitoring and/or control system comprises at least one first device comprising a transmitter/transceiver, and at least one second device comprising a receiver/transceiver, whereby the at least one first device is configured to wirelessly transmit at least one signal to the at least one second device. The at least one first device is configured to transmit the at least one signal at a frequency that corresponds to a resonance frequency of the at least one winding of the electromagnetic device, whereby the electromagnetic device is thereby configured to be used as a passive repeater for the at least one signal that is transmitted.
