ABSTRACT:
A prefabricated ground mat with cathodic protection adapted to protect persons from induced electrical potentials in a pipe or other electrical conductor buried below a ground-level surface, adapted to protect test stands, valve sites, metering stations, pig launchers and receivers, access portals, or other exposed, above-ground equipment which are electrically connected to the buried conductor, from such electrical potentials, and adapted to protect the buried conductor from oxidation due to the ground grid. Multiple mats may be buried between the underground conductor and the ground-level surface and electrically connected to either the underground conductor, the above-grade buried conductor, or both. The mats are made of materials such that the galvanic cell formed by the electrical union of the underground conductor with the mat cause the mat to be consumed. The present invention includes a method of protecting persons and exposed, above-grade equipment from induced electrical potentials in the buried conductor.
