  • System for monitoring cathodic protection system of marine installations including an improved reel
    Patent number: 4581497
    Abstract: An improved system for monitoring cathodic protection systems for marine installations wherein a reference electrode is utilized to measure and periodically monitor the cathodic reference potentials. The reference electrode is connected to one end of a cable and the opposite end portion of the cable is operatively connected to a reel. The reel is connected electrically to the marine installation through a voltmeter and the voltmeter provides readouts of the measured cathodic reference potentials. The present invention includes an improved reel which includes a contactor assembly adapted to maintain electrical continuity between the reel and the voltmeter as the cable is being wound onto and unwound from portions of the reel.
