Abstract
The distribution line to send the electricity to its users is the enormous facility and it is exposed to the severe natural environment. Therefore, cracks may arise in the distribution line.´ However, it is impossible to discover the cracks by visual observation because of the insulator and the protective covering. Grasping the degradation situation of the distribution line is one of the important problems. This paper presents a proposed method for detecting the cracks non-destructively by measuring the magnetic field around the distribution line.
