    A Review on the Lifetime Estimation Methods of XLPE Power Cables by Mohammad AlShaikh Saleh (22467046)

    Published 2025
    “…This article first briefly delves into the various aging mechanisms experienced by power cables, describing the physical and chemical processes that underlie the degradation of XLPE cable insulation over time. The discussion then extends to various life models: physical life models that describe material property changes under operational stresses, phenomenological life models and multistress models that consider the concurrent impact of multiple stressors on cable aging, and probabilistic and reliability lifetime models, which introduce a statistical perspective to the remaining lifetime estimation, essential for risk assessment in power systems. …”
