Claims19
A system configured to provide cathodic protection to buried or submerged metallic structures, comprising a cathodic protection apparatus having at least one upright support and a plurality of sacrificial anodes secured to the at least one upright support in a vertical orientation to provide variable cathodic protection to the metallic structures.
A system configured to provide cathodic protection to metallic structures contained in an underground vault where water levels within the vault rise and lower, the system comprises a plurality of sacrificial anodes secured to a wall of the vault, the sacrificial anodes being electrically connected to each other and arranged in a vertical orientation to provide variable cathodic protection to the metallic structures as the water level in the vault changes.
A method of providing cathodic protection to a metallic structure contained in an underground vault, comprising the steps of:
- (a) providing a plurality of sacrificial anodes;
- (b) securing the plurality of sacrificial anodes in the underground vault in a vertical orientation;
- (c) electrically connecting the plurality of sacrificial anodes to the metallic structure to be protected;
- and
- (d) monitoring a health of the plurality of sacrificial anodes.
