分析了管道阴极保护电位测量产生误差的原因, 论述了瞬间断电法、极化探头的原理, 结合工程实例, 对比了瞬间断电法、极化探头法在埋地钢制输气管道阴极保护参数的测量效果, 总结了两种方法使用过程中需要注意的事项。

Pipeline cathodic protection potential measurement is analyzed and the reason of the error of the principle of instantaneous power method, the polarization of the probe is discussed. Combined with the engineering example, the instantaneous power method, polarization probe method in buried steel pipeline cathodic protection parameters measurement result is compared, the matters needing attention in the process of using two methods is summarizes.
