Comparative study of space charge in the polymeric insulation of power cables using PEA, isothermal and non-isothermal currents measurements

Abstract

An understanding of space charge build-up in the polymeric insulation of power cables is important in determining how aging occurs and progresses and, also in predicting cable lifetime. In this investigation electric-field induced space charge in peelings from XLPE (cross-linked polyethylene) cables was measured using two different methods: the pulsed… (More)
