Abstract
In order to eliminate the interference of regional cathodic protection system to line cathodic protection system,make the line cathodic protection system normally operate with constant potentials,numerical simulation of cathodic protection potential distribution and interference simulation calculation of three-dimensional geometric model were used to analyze the interference,and the simulation was verified by field test.The interference was managed effectively through the results of simulation and field test,the interference between regional cathodic protection system and line cathodic protection system was elimited,the output parameters of line constant potential rectifier were recovered to the level before interference.
