Abstract: In a first aspect of the invention there is provided a method of monitoring a long electric fence from an electrical start of the fence which includes the steps of applying a voltage pulse to the fence, obtaining a measure of the 5 applied pulse voltage, obtaining a measure of current flowing to the fence, processing the voltage measurement and the current measurement to obtain a measurement of real power flow and of reactive power flow to the fence and comparing the real power flow and the reactive power flow measurements to reference values thereby to detect a change in a load on the fence 10 Class: H05C; HO3K Fig: I C-4A |
