New system for artificial ageing of MV cables under controlled conditions

A reliable maintenance and investment strategy is strongly dependent on the determination of the electrical equipment´s condition and is therefore directly connected to characteristic parameters delivered e.g. by partial discharge (PD) and tan(δ) analyses. A specially designed ageing system has been developed to obtain the most accurate method for the ageing of MV PILC (paper isolated lead covered) cables and its diagnostics. It facilitates the control and the monitoring of the entire ageing process and the later development of sophisticated diagnostic criteria based on the physical ageing process. In this paper, the results of the system and cable pre-test, which has been lasting for six months are presented.
