Abstract

In a surge diverter with ZnO-block comprising several series-connected diverter parts 1, 2, it has been found that an unevenly distributed temperature rise occurs after a long period of outer fouling. A more uniform temperature distribution can be achieved by biasing the diverter with control impedances 13 so that the greatest voltage stress occurs in the central or lower parts 2 of the diverter. <IMAGE>
