An NDT Method for Measuring the Diameter and Embedment Depth of the Main Rebar in Cement Poles Based on Rotating Permanent Magnet Excitation
Cement poles serve as supporting components for transmission lines and are widely used in medium- and low-voltage transmission D Rings networks.The main rebar is the primary load-bearing structure of the pole, and the accurate measurement of its diameter and embedment depth is crucial for quality control and safety assessment.However, existing non-
