Coupler for coupling high-frequency EM energy with cables

A system for monitoring cables comprising:

• a coupler for coupling high-frequency EM energy with a high or a medium voltage cable, comprising:
• a ferrite clamp comprising a ferromagnetic non-conductive material capable of signal impeding and configured to encompass a grounding wire of a shielded cable;
• a first sensing connector;
• and
• a second sensing connector, in two alternative configurations,
• a) the first sensing connector is connected to the grounding wire near a first side of the ferrite clamp and the second sensing connector is connected to the grounding wire near a second opposite side of the ferrite clamp;
• or
• b) the first sensing connector is connected directly to a grounding element, and the second sensing connector is connected to a conductive sheath placed on an outside of the high-voltage or medium-voltage cable's jacket;
• and
• a transceiver connected, at either configuration a) or configuration b) to the first sensing connector and the second sensing connector, and configured to be connected to one or more monitoring systems.
