Analysis of Free Energy Increment for Insulation Aging in Crosslinked Polyethylene DC Cable

Abstract: Electrical aging limits the reliability of crosslinked polyethylene DC cable. The study on the reaction kinetics of electrical aging is an important basis of improving the reliability of DC cable. Free energy increment (FEI) under electric field reflects the reaction rate of electrical aging, which is very useful to analyze the aging characteristics of materials. However, there is no direct way to get the FEI, which causes that the FEI stays at the stage of theoretical analysis and cannot be obtained by experi… Show more

“…On this basis, a comprehensive evaluation model of cable operating status with improved radar chart theory was established [14]. An analysis method combining fuzzy theory and analytic hierarchy process has been introduced to evaluate the cable status based on the particularity and difference of different influencing factors [15], and on the basis of the evaluation results, a maintenance strategy considering economy and reliability is formulated [16]. The insulation resistance, dielectric loss angle and partial discharge of the disabled cables and their accessories were comprehensively measured.…”
