摘要
理论分析土壤电阻率和涂层缺陷电阻等参数对埋地管道阴极保护电位测量时IR降误差的影响 ,建立IR降电阻因子计算模型 ,并用实验数据验证 ,此外 ,还讨论了IR降误差的工程预测方法 .
The influence of soil resistivity and coating defects on IR drop error in cathodic protection(CP)potential measurement was studied by theoretical methods.Calculation modeling was established and proofed by some test data for resistance factor of IR drop.In addition,engineering prediction methods for IR drop were also discussed.
