摘要
介绍了一种新型的极化试片电流测试方法。该技术采用高精度数据记录仪监测受到动态直流杂散电流干扰的极化试片中流进、流出的直流电流。该结果可以用于埋地钢质管道直流杂散电流干扰的评价,为查找直流杂散电流干扰腐蚀风险点提供依据。
A new method for measuring DC current through coupon is introduced. A high accuracy data logger was used to monitor the DC current that was picked up or discharged by coupon. This method could be implemented in the evaluation of dynamic stray current interference and may provide valuable information for identification of corrosion risk points on buried pipeline.
