Abstract :
The problem of the evaluation of the buried cable thermal useful life in presence of harmonic distortion and taking into account the moisture migration is analysed. The evaluation is effected in nondeterministic scenario with a probabilistic approach. Numerical applications referred to medium voltage cables are presented and discussed in order to show the influence of the harmonics and moisture migration on the cable useful life.
