Frequency Dependence of the Electric Field Grading of End-Winding of Generator Bars
Aakre, Torstein Grav; Enoksen, Henrik; Eberg, Espen; Mermigkas, Athanasios; Hølto, Jorunn (Peer reviewed; Journal article, 2022)To reduce the electric field stresses in the end-winding in hydropower generator bars, a field dependent grading tape is applied in the transition zone from outer corona protection to bare insulation. The design is typically ... -
Modelling of Internal Pressure Dynamics in Mass-Impregnated Non-Draining HVDC Cables
Hestad, Øystein Leif Gurandsrud; Runde, Magne; Enoksen, Henrik; Magnusson, Niklas (Peer reviewed; Journal article, 2022)Changing the current loading of mass-impregnated non-draining power cables causes the pressure in the insulation to vary over a wide range. It is generally recognized that under certain conditions—typically after a large ...
