Points to consider regarding the insulation coordination of GIS substations with cable connections to overhead lines by
M. M. Osborne, A. Xemard, L. Prikler, J. A. Martinez :
Abstract : Gas Insulated Switchgear (GIS) when coupled with
short cables complicates insulation co-ordination practice
particularly regarding fast front transients. The impact of an
over-voltage in GIS can be worse than air insulated switchgear ,(AIS), since a flashover in solid insulation or GIS can result in ............... |
