CP Potential Measurement and Evaluation of Pipeline Undergoing Dynamic DC Stray Current Interference from Metro System
摘 要
对于受地铁动态直流杂散电流干扰的埋地钢质原油管道,采用试片电位采集仪测量了阴极保护极化试片的断电电位。结果表明,该测试方法简便易行、数据准确可靠,与传统测试方法相比具有较大的技术优势。
Abstract
For the buried steel crude oil pipeline being interfered by the dynamic DC stray current of subway, a test potential collector was used to measure the power-off potential of cathodic protection polarization test piece. The results show that the test method was simple and easy, the data was accurate and reliable, and it had greater technical advantages compared with the traditional test method.
