Coupled Electric-Thermal-Fluid Analysis of High Voltage Bushing

G. Eriksson[1]
[1]ABB, Corporate Research, Västerås, Sweden

Modern power transmission systems are in general designed to operate at high voltages in order to reduce resistive losses generated by high currents. This, however, tends to increase the risk for dielectric breakdown or flashovers if the equipment is not properly designed to withstand ... Per saperne di più
