Abstract
A stray voltage detection and reduction system. The stray voltage detection portion of the system includes a vessel configured to hold a liquid, such as water. An electrode is suspended in the water, and another electrode is positioned below the vessel in contact with the earth. A meter is coupled to the electrodes in such a manner that when an animal drinks from the vessel the presence or absence of stray voltage is detected by the meter. The stray voltage reduction portion of the system electrically isolates a water distribution system. A water source is connected to non-electrically-activated valves. The valves feed a plurality of storage tanks. The storage tanks connect to non-electrically-activated valves which are coupled to a booster pump. A control system ensures that the water source remains electrically-isolated from the booster pump.
