A monitoring system for use with an electrified fence and an energizer (21) therefore, said monitoring system being adapted to determine the effectiveness of electric pulses applied to the fence by the energizer (21) and comprising voltage sensing means (10) for sensing the voltage of the pulse applied to the fence conductor, current sensing means (12) for sensing the current in the fence conductor and monitoring means (14), (16), (17), (20) for monitoring signals related to the current and voltage whereby the monitoring means (14), (16), (17), (20) operates an alarm means (18) and/or indicates a reading on indicator means (15) when the monitored signals fall outside predetermined ranges of values indicative of lack of fence effectiveness. |
