INTRUSION DETECTION SYSTEM FOR ELECTRIC FENCES

摘要

An energizer for an electric fence having a wire with feed and return terminals. The energizer includes a high voltage pulse generator for generating high voltage pulses at the feed terminal and a low voltage circuit for providing a low voltage signal at the feed terminal and for monitoring any changes in the low voltage signal at the return terminal to determine if the wire of the fence is touched, or if a short circuit or open circuit exists. An impedance decouples the high voltage pulses from the low voltage circuitry. The low voltage circuit makes measurements of electrical characteristics of the wire between the high voltage pulses. A low voltage intrusion detection system and related methods are also disclosed.
