Decoupling Tank Grounding Systems

Local tank grounds, as well as grounding conductors for electrical equipment, will tie the cathodically protected tank to additional in-earth structures, requiring excessive CP current. The tanks must be locally grounded to protect your equipment and your personnel. However, the bond to ground will drastically increase the amount of CP current needed to prevent corrosion. How can you maintain both lightning protection and CP efficiency?

All Dairyland products provide excellent over-voltage protection for lightning effects, as well as AC faults, and block CP current that would otherwise short to your tank grounds. If your tank farm uses insulated joints to aid in DC isolation, the life and quality of the joint can be protected using a Dairyland product. Dairyland’s rugged solid-state construction and fail-safe design will ensure your tank has reliable CP levels and over-voltage protection in place.
