Sacrificial Anode Test Station

sacrificial-anode-panel-tankThis special junction box was developed specifically for the water storage tank market. It is used for small sacrificial anode Cathodic Protection systems to control the current from the sacrificial anodes to the tank and monitor the structure to reference electrode potential level.

  • The standard Sacrificial Anode Control Test Station enclosure is constructed from white fiberglass reinforced polyester (FRP) that is UV stabilized and conforms to a Type 4X rating. A limited variety of alternate enclosure materials and finishes available (including uncoated Type 316 stainless steel and white powder coated marine grade aluminum).
  • The test station allows access to the internal components via a single front hinged door on the standard enclosure. The test station components are assembled onto a single removable panel type assembly.
  • The test station utilizes a digital LCD type meter powered by a standard 9 volt battery for monitoring of the sacrificial current and the structure to reference electrode potential. The meter is normally powered “off “ and is isolated via the use of a “normally off” type switch. When in use, the LCD meter has an input impedance of > 10 megaaohms.
  • The test station has a current control section that includes a rheostat (variable resistor) that is manually adjusted by the operator to control the sacrificial anode current to the tank structure. The current level is displayed on the LCD meter by the flick of a “normally off” switch. The current control section also includes a “normally on” switch which allows the operator to momentarily switch off the sacrificial anode current and thus obtain an instant off “IR-Drop Free” potential reading.
  • The test station potential monitoring section offers inputs for two reference electrodes that may be situated within the interior of the water tank. A switch is supplied to allow the selection of either reference electrode input. By the flick of a “normally off” switch, the structure to reference electrode potential can be monitored on the test station meter.

This self-contained test station minimizes the client’s need for a portable external meter to monitor the current and potential level of their system. Also, though this test station was designed for the water storage tank market, it can be used in conjunction many other sacrificial anode systems.
