Stray voltage, or “leakage current” as we prefer to call it, is an issue becoming more prevalent in the dairy industry. As our industry utilizes more electronic equipment that increases the efficiency of our operations and reduces operating costs, such as variable speed drives (VSDs), electronic ballast lighting, variable speed fans and ventilation, we are actually increasing the sources of possible stray voltage. Faulty wiring, defective equipment, bad connections and electrical arcs are also sources that may cause stray voltage on a facility at any time.
