초록
We used eddy current sensor for diagnosis of power line. The power line according to the cross section has 6~18 element wires. The corrosion of power line was made by sodium hydroxide. The corrosion time of power line was from 18 hours to 27 hours. We obtained physical characteristics from tensile and torsion tests of power line. The eddy current Characteristics of power line according to the corrosion appeared change of amplitude 200 ~ 800 mV.
