Inner defect depth detection using a multifrequency alternating current potential drop technique
The alternating current potential drop technique is usually used to monitor surface defects in metal structures by taking advantage of the skin effect. However, defects often occur in the inner walls of oil or gas pipes as a result of corrosion or erosion. In this work, a multifrequency exciting cur...
