We used the eddy current sensor for a 22.9㎸ distribution power line insulation cable diagnosis. The insulation cable which is used in the 22.9㎸ distribution power line is having element wire from 6 to 18. Consequently, currently to ECT applications it has a limit in the distribution power line. We about under producing to apply in pick-up coil forms and the differential total coil form where becomes sum of zero in order to have. From measurement result, partial broken cable was confirmed 500 ㎷ ~ 980 ㎷ changes from normal state.
