Abstract

Abstract

The equation of negative shift “E₀” of pipe/ground potential at connection point, the relation-ship between potential attenuation coefficient “a” and calibration coefficient “r” as well as electric conductivity “g₁” of coating are dedueecl by systematic analysis a vast amount of experimental data collected from cathodic protection system of underground pipelines with sacrificial anodes.
