Substation Corrosion Management


Project 37.104

Program At-a-Glance

Ground grid integrity is a critical factor governing the safety and reliability of a substation or switchyard. Copper is the typical material used in the construction of a ground grid due to its corrosion resistance in most soil series. Degradation of the grid, however, can still occur when used outside the design specifications or in soils that are chemically incompatible. What existing tools or techniques can identify locations within the ground grid that do not meet the design specifications and represent risk to the utility?
