Corrosion protection methods for the protection of the national infrastructure of copper/iron, copper, lead/iron potable water distribution systems

摘要

A methods and system to lower the grounding potential of an AC electrical grid for protecting a potable water delivery system from corrosion. This can be achieved through the addition of chemical to the water system or via corrosion protection systems such as cathodic protection, impressed current protection. These methods are also effective in corrosion protection of the national metallic infrastructure, such as street signs, lights stands, bridges, and any systems connected to the electrical grid.
