Research to Develop Guidelines for Cathodic Protection of Concentric Neutral Cables. Interim Report
The objectives of this project were to determine and statistically analyze data associated with corrosion of concentric neutrals (CN) of direct buried primary cables, and develop guidelines for cathodic protection of CN for the electric utility industry. This interim report includes descriptions and results of field testing conducted at 36 bellholes excavated in California, Oklahoma, and North Carolina. It also includes details of the electrochemical, chemical, bacteriological, and sieve analyses of native soil and imported backfill samples. Up to 129 values were determined for each bellhole and stored on cards as a data bank. All values were statistically analyzed and correlated with corrosion found. The severity of corrosion correlated best with CN corrosion potentials, CN resistance measurements, coarseness of backfill, and soil resistivity. The guidelines for installation of cathodic protection on CN cables will be completed for publication in July 1981. They will be based upon the evaluation of over 100 experimental cathodic protection systems and upon laboratory testing for protection criteria with and without ac effects. (ERA citation 06:033280)
