A current/voltage sensing node 11-17 which includes a sensing circuit and a data interface which on detection of the voltage/current being removed from cabling 50, a data signal 10 is generated and sent via a sub-gigahertz transceiver to a remote station 20 and then to a recipient 31 or control room 30. The station may be part of a network including a repeater or a base station 20. A public address message may also be transmitted using the network to alert a warning of a fault. The non-intrusive monitoring of voltage carrying electric cables and in particular but without limitation to monitoring the theft, loss of power or damage to high voltage cables, but without limitation to, all electric cables capable of carrying an electric current. |
