Abstract

Detecting cracks in a power distribution line non-destructively will be possible through proposed evaluation of the magnetic field distribution around the line when it is energized. The authors have examined and simulated the distribution of the magnetic field around a conducting wire. They confirmed the feasibility of this method and suggested that the optimum search coil width is about 2 mm when the crack is 1.0 mm wide and 1.5 mm deep from the results of the simulation.
