Subsequently, this article provides analysis of these three methods, including analysis and comparison of their advantages and disadvantages. Finally it proposes a new method based on ultrasonic guided wave method and then explores its feasibility and ad-vantages. %K Grounding grids corrosion diagnosis %K electromagnetic theory %K electromagnetic theory %K electrochemical method %K ultrasonic guided wave %U http://www.ijcee.org/papers/720-SE3011.pdf
