An evaluation of insulation and switching media in medium voltage (1-52 kV) applications is presented in this paper. Special attention is given to motor switching and to distribution of electricity. The various insulating and/or switching media like oil, epoxy resin, air, SF6 and vacuum are discussed. The various arcing media in medium voltage grids have evolved to a mature situation nowadays, and the pro's and con's of the various media in different applications are presented. Key words are

The basic phenomena, such as current chopping and restrikes are reviewed and the harm that overvoltages can cause either by amplitude or rising time to the equipment. Besides the overvoltage aspects, the operation & maintenance aspects related to different insulating and switching media are surveyed and discussed. Index Terms -vacuum, SF6, insulation media, arc quenching media.
