摘要
The device is an electrically insulating tube which is rigidly mounted between the ends of two dissimilar metal pipes. Longitudinally spaced, annular electrodes are mounted in grooves formed in the cylindrical interior wall. The electrodes are electrically connected to the fluid within the chamber. The chamber is defined by the interior walls of the pipes and the tube. A current source is electrically connected to the electrodes, for generating a current between the electrodes, creating an ohmic potential drop in the fluid that minimizes the potential shift of the pipes from that naturally existing in the absence of the dissimilar metal couple. Sensors sense the naturally existing potential of the pipes for varying the current between the electrodes.
