Abstract
High speed cathodic protection control systems and methods provide for the delivery of deliver electrical current to a group of metal structures, such as well casings, in a sequential manner to prevent corrosion. A plurality of relays allow electrical current to flow from a power supply to subsets of the group of metal structures. The flow of electrical current is controlled by a microntroller which controls the relays to allow delivery of the electrical current at high speeds for short periods of time from the power supply to subsets of the group of metal structures in a sequential manner.
