Editorial: 15th International Conference “Dielectric and Insulating Systems in Electrical Engineering - DISEE” – septemper 8 – 10, 2004, Casta Pila - Slovak Republic, ISBN 80-227-2110-7, p.83 - 86, 2004.


This paper presents the obtained results following implementation, on some underground medium voltage power lines from Cluj city – Romania, of an original protection system, which assures as well the anticorrosive protection of metallic screen sheets as the increase of the exploitation cables’ insulation resistance by “inverted electrochemical treeing” of ionic charge carriers from within insulator’s volume toward its screen.
