Influence of SiO2 and ZrO2 Nanocomposite on the AC Breakdown Strength of Cross-linked Polyethylene (XLPE)

2021 IEEE International Conference on the Properties and Applications of Dielectric Materials (ICPADM), 2021
Evolution of high voltage (HV) cables has increased significantly over the last decade due to emerging of HVDC applications. Thus, polymer nanocomposites become one of the main research areas for exploring the potential of insulating materials in terms of dielectric strength enhancement.

Mechanism of space charge formation in cross linked polyethylene (XLPE) under temperature gradient

IEEE Transactions on Dielectrics and Electrical Insulation, 2015
A bipolar charge transport model is used to simulate the formation of space charge in XLPE plaques placed under a temperature gradient. The model is used to assess the relative importance of charge migration and blocked extraction for three possible effects of the temperature gradient.

Influence of accelerated aging on mechanical and structural properties of cross-linked polyethylene (XLPE) insulation

Electrical Engineering, 2001
This paper describes results of laboratory accelerated aging test and the influence of different aging conditions on non-electrical properties of cross-linked polyethylene insulation (XLPE). Accelerated aging has been carried out on a cable model with different electrical and thermal stresses, and with thermal stresses in air or water as surrounding ...

Characterization Tests and analysis of cross-linked polyethylene (XLPE) used in high voltage cables insulation under thermal constraint

2014 International Conference on Electrical Sciences and Technologies in Maghreb (CISTEM), 2014
High voltage cables are permanently subjected to electrical and thermal operating constraints, leading to their progressive degradation and deterioration. The control and the identification of the thermal aging parameters of high voltage insulation require the use of several characterization techniques.
