This study aims at estimating for the first time the life in HVDC Mass-Impregnated Non-Draining MIND cables subjected to Prequalification Test (PQT) conditions according to CIGRÉ Technical Brochure 853-2021. A MATLAB simulation is carried out to calculate temperature and electric field distribution within MIND insulation during PQT Load Cycles, and to estimate cable insulation life under PQT conditions. The results show that estimated life of MIND cables under PQT conditions is far longer than the duration of the PQT (360 days), as well as longer than that previously estimated under the same conditions for extruded cables.

Abstract
This study aims at estimating for the first time the life in HVDC Mass-Impregnated Non-Draining MIND cables subjected to Prequalification Test (PQT) conditions according to CIGRÉ Technical Brochure 853-2021. A MATLAB simulation is carried out to calculate temperature and electric field distribution within MIND insulation during PQT Load Cycles, and to estimate cable insulation life under PQT conditions. The results show that estimated life of MIND cables under PQT conditions is far longer than the duration of the PQT (360 days), as well as longer than that previously estimated under the same conditions for extruded cables.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
