Abstract
An active cathodic protection system, the apparatus comprising a rectifier element with at least one electrical connection to a source of electrical current, the rectifier element associated with a direct current positive (+) output terminal for electrical connection of via an anode connector to a consumable anode, a direct current negative (−) output terminal for electrical connection via a cathode connector to the structure to be protected, grounding means for electrical grounding of the apparatus and anti-cross connection means for preventing the continuing flow of electrical current when the anode connector is associated with the negative output terminal and the cathode connector is associated with the positive output terminal.
Claims15
An active cathodic protection system, for the protection of a non-isolated structure, comprising:
- a consumable anode;
- a rectifier element with at least one electrical connection to a source of electrical current, said rectifier element including a direct current positive (+) output terminal connected to said consumable anode, said anode connector and further including a direct current negative (−) output terminal connected to said non-isolated structure via a cathode connector;
- an electrical safety grounding device for electrical safety grounding of said non-isolated structure;
- and
- anti-cross connection device for preventing the continuing flow of electrical current when said anode connector is associated with said negative output terminal and said cathode connector is associated with said positive output terminal.
A method of transporting and installing an anode in a hole in the ground, comprising the steps of:
- securely attaching said anode to a container;
- filling said container with a predetermined amount of backfill material for a particular anode hole size;
- transporting said container and said securely attached anode to potential hole site;
- digging an anode hole corresponding to the amount of backfill material provided in said container;
- removing said anode from said container;
- placing said anode in said anode hole;
- removing said predetermined amount of backfill from said container;
- and
- placing said predetermined amount of backfill from said container into said anode hole.
