    • 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.
    • 杂散电压检测和还原系统。 系统的杂散电压检测部分包括构造成容纳诸如水的液体的容器。 电极悬挂在水中,另一个电极位于与地球接触的容器的下方。 仪器以这样的方式耦合到电极,即当动物从容器中饮用时,仪表检测到杂散电压的存在或不存在。 系统的杂散电压降低部分将配水系统电隔离。 水源连接到非电动活化阀。 阀门供给多个储罐。 储罐连接到与电动泵相连的非电动活动阀。 控制系统确保水源与增压泵保持电隔离。

    • A stray voltage detection and isolation system. The stray voltage detection portion of the system includes a water delivery system electrically isolated from an electrical transmission system of an electric utility. Meters measure an electrical characteristic between a first test-point that is electrically connected to the water delivery system and a plurality of second test-points. The second test-points are at earth grounds at locations electrically connected to the first test-point. The location of a source of stray voltage can be determined by evaluating differences in the measured electrical characteristics. The stray voltage isolation portion of the system electrically isolates a water delivery system. A controller maintains an air gap between a water source and a first storage tank or between the first storage tank and a second storage tank. The second storage tank provides the electrically isolated water.
    • 杂散电压检测和隔离系统。 系统的杂散电压检测部分包括与电力公司的电力传输系统电隔离的输水系统。 仪表测量与水输送系统电连接的第一测试点和多个第二测试点之间的电特性。 第二个测试点位于电连接到第一个测试点的位置的接地处。 杂散电压源的位置可以通过评估测量的电气特性的差异来确定。 系统的杂散电压隔离部分电隔离供水系统。 控制器在水源和第一储罐之间或者在第一储罐和第二储罐之间保持气隙。 第二个储罐提供电隔离的水。
