HIGH SPEED SEQUENTIAL CATHODIC PROTECTION SYSTEMS AND METHODS

摘要

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.

1. A high speed sequential cathodic protection system for delivering electrical current to a group of underground metal structures comprising a plurality of individual metal structures to prevent corrosion of the metal structures, the system comprising:
a power supply; a plurality of individual relays adapted to allow electrical current to flow from the power supply to subsets of the group of metal structures; and a microcontroller configured to control 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.
