Abstract
Various inspection methods of efficiently detecting flaws on overhead transmission lines caused by lightning or long-term fatigue were studied. The results suggested that an electromagnetic induction method would be highly feasible for detecting flaws. Consequently, a new detector that uses the electromagnetic induction method has been developed to locate and detect the degree of flaws. The results of laboratory and field tests using the newly developed flaw detector are described. The detector was found to be a quick and accurate tool for inspecting flaws on power conductors
