TitleBringing an insulation to failure: The role of space charge

Abstract— Considering the title of this paper, one might think that everything has been said, shown, proven and discussed already on ageing and failure of electrical insulating materials, based on at least half century of research work and field feedbacks. However, perhaps there is still room to collect ideas and speculate on apparently proven or brand new concepts, such as the interrelation between ageing mechanisms and physically measurable quantities as space charge and conduction current. The latter is, indeed, the scope of this paper. On one hand we will revisit the concepts of space charge accumulation in insulating (polymeric) materials, considering also the last achievements which deal with ultra-fast charge pulses (solitons), on the other hand we will discuss how space charge can contribute directly or indirectly, through local electric field magnification or alteration, to increase ageing rate or even trigger more energetic, thus faster, degradation processes (from partial discharges to thermal instability breakdown). The goal is, at the very end, to show how much such basic investigations can have a fundamental impact on insulation design and electrical apparatus long-term performance/reliability.

Prof. Gian Carlo Montanari short Bio: Gian Carlo Montanari (M’87-SM’90-F’00) was born on 8 November 1955. In 1979, he took the Master degree in electrical engineering at the University of Bologna. He is currently Full Professor of Electrical Technology at the Department of Electrical Engineering of the University of Bologna, and teaches courses of Technology and Reliability. He has worked since 1979 in the field of aging and endurance of solid insulating materials and systems, of diagnostics of electrical systems and innovative electrical materials (magnetics, nanomaterials, electrets, superconductors). He has been also engaged in the fields of power quality and energy market, power electronics, reliability and statistics of electrical systems. He is a member of AEI and Institute of Physics. He is a member of the AdCom of the IEEE DEIS. Since 1996 he is President of the Italian Chapter of the IEEE DEIS. He is convener of the Statistics Committee and member of the Space Charge, Multifactor Stress and Meetings Committees of IEEE DEIS. He is an Associate Editor of IEEE Transactions on Dielectrics and Electrical Insulation. He is founder and President of the spin-off TechImp, established on 1999. He is author or co-author of about 550 scientific papers.
