Estimate the temperature rise of medium voltage metal enclosed switchgear by simplified heat transfer calculations
Fjeld, Elin; Rondeel, Wilhelm G. J.; Attar, Elham; Singh, Shailendra (Journal article; Peer reviewed, 2020)Electrical equipment will experience a rise in temperature during normal operation. During a development process, prototypes and laboratory tests will be required to make sure the temperature rises are within acceptable ... -
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 ...
