Abstract
Carbon black paper screens have been used over the conductor and over the insulation of high voltage cables. This causes a stress dependent rise in tan 5 of the cable which is shown in this report to be related to conditions at the carbon black (CB) paper-insulating paper interface, and not to losses within the body of the CB paper layer. A "cold-emission" of electrons is postulated to account for the observed effects of CB paper on tan δ.
