Abstract

Loss of insulation integrity from a gas-insulated system is at first a subtle phenomenon. It is contended that this early stage of degradation contains privileged information, to be gleaned in order to unravel precursor signs preceding the eventual outbreak of minor faults, viz. partial discharges and associated patterns.
