1. An anti-theft system for an electric power cable comprising:

  • a radio transmitter for generating a notification to a predetermined recipient; and

    a conductive sensing loop having first and second ends, said sensing loop installed in at least one conduit with the power cable, wherein at least one portion of the sensing loop is formed by running two conductors through a conduit alongside the power cable and connecting first ends of the conductors at a first end of the conduit;

    an alarm circuit coupled to said radio transmitter, said alarm circuit comprising;

    a first circuit for supplying a continuous voltage to said first end of said conductive sensing loop; and

    a second circuit for detecting said continuous voltage at said second end of said conductive sensing loop and triggering said notification by providing power to said radio transmitter when said continuous voltage is disrupted.
