Abstract
An electric fence controller having a capacitor which can be charged to a predetermined voltage. A timer which discharges the capacitor at fixed intervals of time and a transformer, the primary of which is connected across the capacitor and the secondary of which is connected to a load and to an impedance connected to the primary or secondary of the transformer. The impedance when measured at the operating voltage from the secondary terminals of the transformer is less than the normal fence line impedance.
