Disclosed is an electric fence energiser including a measurement and control circuit (8) comprising: means for the periodic measurement of at least one electric parameter characteristic of the instantaneous impedance at the terminals of the energiser, using a sufficiently short period so that the measurement can be repeated multiple times during the pulse; comparison means for comparing the results of the measurement of the at least one parameter to reference values; and control means which can instantly alter the characteristics of the current pulse so that it does not pose a danger to people in the event of a deviation between the measurement results and the reference values, which deviation may indicate that a person has come into contact with the fence (6).
