Travelling waves in high-voltage alternator windings [PDF]
Journal of the Institution of Electrical Engineers - Part II: Power Engineering, 1942 The security of the windings of an alternator generating at 22 kV or above and connected directly to a network depends mainly on the ability of the insulation to withstand surge voltages. The distribution of surge voltages in the various types of stator winding hitherto adopted in commercial practice is examined, together with the relation of this ...

Analytical Estimation Method of Winding Parasitic Capacitance for High-Frequency High-Voltage Application [PDF]
IEEE Access, 2020 Aiming to calculate the winding parasitic capacitance for high-frequency high-voltage application, this paper proposes an improved energy method by dividing the electrostatic field into several energy regions. Analytical models of the divided energy regions are established based on the assumed electric field distribution.
