FENCE CONDITION MONITORING APPARATUS AND METHOD

摘要

The invention provides a monitoring apparatus adapted to monitor the condition of a fence line (4). It includes a reference signal generator (1), and an interface adaptor (2) configured to place a reference signal on a fence line. This interface adaptor has a connection to the reference signal generator which provides isolation of the reference signal generator from the fence line, the interface adaptor places a reference signal on the fence line remote from the location of an electrical load (6) present on the fence line. The monitoring apparatus also includes a detection system (3) to receive a translated signal from the interface adaptor where this detection system has a connection to the interface adaptor which provides isolation of the detection system from the fence line. The system indicates the condition of the fence line monitored through the state of one parameter associated with a translated signal received by the detection system.
