Abstract

Recent progress in the research and development of electrical insulation for modern electric power systems is reviewed. Cross-linked polyethylene cables, gas-insulated switchgear, composite insulators and oil-immersed transformers are covered. A number of aging processes are presented and analyzed. Typical aging processes are considered to be due to tree formation, partial discharge, electrochemical processes and thermochemical processes. Almost all causes of aging have been itemized and have been phenomenologically verified. Several other theoretical aspects that need to be clarified are identified
