Abstract
The impulse strength of TR-XLPE cable has been reported to drop to a greater degree than the AC strength as a function of time during service aging. In this contribution, we discuss the mechanisms by which the impulse strength can degrade to a much greater degree than the AC strength. Three frequency dependent mechanisms have been identified which include electro-thermal, electro-mechanical, and electrical
