Electromagnetic Device & Condition Monitoring And/Or Control System, Method & Use

Abstract: An electromagnetic device (10) comprising a magnetic field-generating electric circuit comprising at least one winding (12), and a system (24) configured to monitor a condition of the electromagnetic device (10) and/or to control the electromagnetic device (10). The condition-monitoring and/or control system (24) comprises at least one first device (26) comprising a transmitter/transceiver, and at least one second device (28) comprising a receiver/transceiver, whereby the at least one first device (26) is configured to wirelessly transmit at least one signal (18) to the at least one second device (28). The at least one first device (26) is configured to transmit the at least one signal (18) at a frequency that corresponds to a resonance frequency of the at least one winding (12) of the electromagnetic device (10), whereby the electromagnetic device (10) is thereby configured to be used as a passive repeater for the at least one signal (18) that is transmitted.
