Abstract: An electric fence control unit includes a signal generator, a first signal receiver, a second signal receiver, a signal processing and control unit, and a communications interface. The signal generator generates and transmits an adjustable power signal along a conduction path of the electric fence. The signal receivers sample signal outputs at a driven end and at an open end of the fence line. The signal processing and control unit receives and analyzes the first signal output and the second signal output. The communications interface transmits results from processing the first signal output and the second signal output to a service center. The power signal is adjustable to any capacity power level between a maximum power level and a minimum power level to match a load of the electric fence. Methods of monitoring the electric fence, including adjusting a power level of the adjustable power signal, are also disclosed.

Abstract: An electric fence energizer provides automated reporting of faults and other events as well as fault location to reduce effort in diagnosing faults and intrusion events in electric fences by measuring impedance changes using a time-domain reflectometer. In some embodiments, methods determine the location of a fault in distance from the energizer and provide timely and appropriate condition information.
