Cumulative degradation of electrical properties in polypropylene insulation for AC cables under repeated impulse voltage stress

open access: yesHigh Voltage, Volume 10, Issue 3, Page 623-631, June 2025.
Abstract In modern power transmission systems, AC cables are increasingly integrated with overhead lines, forming hybrid networks. These cables are frequently exposed to repeated impulse voltages from the overhead lines. While surge arresters offer partial protection, the long‐term effects of these impulses on polypropylene (PP) insulation remain ...
