Abstract: Stray voltage reduction system for reducing electrical shocks to livestock in a farm and similar building wherein the system senses a voltage between first and second components, such as metal stall stanchion and metal water trough, of a livestock enclosure or holding area and electrically shorts the first and second components for a preset time period when a stray voltage beyond a preset trigger voltage potential difference is detected between the first and second components. The device includes a voltage sensing circuit for sensing voltage between the first and second components, a comparator, and electrical shorting circuit that can include a relay actuated switch responsive to the output of the comparator when a sensed potential difference between the first and second components equals or exceeds a preset trigger value to electrically short (switch closed by relay) the components for a time to reduce the voltage below the trigger value.
