THE CASE OF PEDERSEN'S THEORY TO MODEL PARTIAL DISCHARGES IN CAVITIES ENCLOSED IN SOLID INSULATION: A CRITICISM OF SOME OF ITS ASPECTS FROM AN ELECTRICAL ENGINEERS' AND FROM A PHYSICISTS' POINT OF VIEW

Michael G. Danikas - George E. Vardakis

   Pedersen's model is a model tackling the problem of partial discharges in solid insulation cavities. The aforementioned model is deduced with the help of the electromagnetic theory and not with the aid of an equivalent capacitance circuit, as is the case for the abc model (called also capacitance or Gemant-von Phillippoff model). Based on some experimental data, it is the aim of this paper to critically examine some aspects of Pedersen's model from an electrical engineers' point of view.Aspects of Pedersen's model are also studied and discussed from a physicists' point of view. Future research plans are outlined.

Keywords: partial discharges, cavities, capacitance circuit, Pedersen's model, streamer criterion
