Abstract

The electric fence has a charging condenser which is periodically discharged through the primary of a transformer to generate high voltages for feeding to the fence in the form of damped pulses whose voltage level can be controlled to an optimum value. To improve the monitoring of the output pulses especially when operating from a battery supply the two first immediately following half waves of the pulse are compared with a reference value. The transformer may be given a pair of auxiliary windings (W1, W2) on the secondary side charging a pair of condensers (C1, C2) through rectifiers (D1, D2). The voltages across these condensers are compared in a comparator (D) and their ratio is compared with a reference value to assure that the damping has not fallen below a preset level.
