Abstract
A voltage detection system for detecting a stray voltage in pool water within a pool caused by an electrical fixture integral with a pool wall of the pool. The system comprises a pair of elongate conductive elements, with one of the elongate conductive elements having a detector electrode end and a terminal end, and with the other elongate conductive element having a reference electrode end and a terminal end. The detector electrode end is positioned adjacent to the electrical fixture and the reference electrode end is positioned on an opposite side of the pool and preferably a maximum distance from the detector electrode end. And, the terminal ends are connected to a microprocessor for determining if a voltage between the detector electrode end and reference electrode end is greater than a predetermined threshold voltage.
