Dyden Corporation, Kurume, Japan, announced that it has developed two types of portable power sources suitable for the maintenance work just described. The two devices are called line electric induction coupler Leicoupler®. The first type is for use in cable manholes, and the other for use with overhead transmission lines. The Leicoupler for cable manholes utilizes electromagnetic induction. When a current transformer (CT), or coils with an iron core at their center, are positioned around a power cable in operation, an electromotive force will appear. Similar power sources using the same principle are already commercially available. The company has also developed a new compact and water-resistant power source that releases excess power in a form other than heat.
