In this paper, the authors investigate the effect of using 3 different macroscopic electrical conductivity equations with the relevant fitting parameters, mostly found and used in the literature for DC-XLPE, on the life of cable. The results show a similar pattern of the DC electric field distribution inside the insulation thickness obtained with the 3 electrical conductivity equations, although they provide a different degree of field inversion. Consequently, the electrothermal life of cable is affected by the conductivity equation used in this process.

Abstract
In this paper, the authors investigate the effect of using 3 different macroscopic electrical conductivity equations with the relevant fitting parameters, mostly found and used in the literature for DC-XLPE, on the life of cable. The results show a similar pattern of the DC electric field distribution inside the insulation thickness obtained with the 3 electrical conductivity equations, although they provide a different degree of field inversion. Consequently, the electrothermal life of cable is affected by the conductivity equation used in this process.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
