Corrosion due to electrochemical reactions and methods for dealing with it are discussed. To estimate the rates of substation ground grid and guy anchor corrosion, four tests are suggested, namely: (1) earth resistivity (2) guy current, (3) grid-to-earth potential; and (4) polarizing current. An analysis of test results will give the degree of corrosion and the form of correction necessary.>
