Abstract :
This paper discusses a study on voltage-life characteristics (V-t characteristics) for XLPE power cables. In order to verify the validity of the lifetime estimates produced by V-t tests, the authors have proposed and evaluated a new V-t testing method in which new techniques of electric degradation luminescence and partial discharge detection methods are applied. As a result, it was found that the evaluation of long-term power cable performance by such V-t tests is justified
