Dry-type High Voltage Capacitors

Abstract

High voltage capacitors are important components of electrical network. The current technology is based foil-laminar coil impregnated in a liquid dielectric. However, there is an interest to develop technologies allowing to replace mineral or synthetic oil due both to health and environmental issues. The feasibility of replacing the impregnating liquid by a solid encapsulating material for HV capacitors is presented in this paper.
