Abstract : A system and method of detecting stray electrical currents that cause corrosion on metallic structures submerged in electrolytic media. The system makes use of a plurality of metal plates in an arrangement so they will be bipolar electrodes in a stray current field and the stray currents are determined by the color of the plates. The amount of stray currents are determined by the amount of metal loss over a period of time. Plates may be placed about a ship's hull, or other submerged structures, or suspended in an open area of solution to locate areas of stray currents. (Author)
