Partial discharge. X. PD in gas-insulated substations-measurement and practical considerations

For pt.IX see ibid., vol.7, no.6, p.5 et seq. (1991). An overview of engineering practice related to partial discharge (PD) measurements in gas-insulated substations (GISs) is provided. The following questions are addressed: why measure PD in GIS?; in which phases of the life cycle should PD be measured?; what PD measurements are presently available?; and, what results can be expected under various measurement conditions?.<
