High current arc erosion on copper electrodes in air
Øyvang, Thomas; Fjeld, Elin; Rondeel, Wilhelm; Hagen, Svein Thore (Journal article; Peer reviewed, 2011)An arc fault inside metal enclosed switchgear will cause the pressure to rise and vaporization of electrode material may contribute to the pressure rise. An experimental study of high current arc erosion on copper electrodes ... -
Thermal Design of Future Medium Voltage Switchgear
Fjeld, Elin; Rondeel, Wilhelm; Vågsæther, Knut; Saxegaard, Magne; Skryten, Pål; Attar, Elham (Conference object; Peer reviewed, 2015)Air is a desirable alternative to SF6 in medium voltage (MV) switchgear. However, the thermal properties of air is poorer compared with SF6, and this paper presents a first step in the process of finding an optimized thermal ...
