Özet
The impact of high-frequency voltage/current oscillations on the corona discharge’s ignition and damping in electrical networks were experimentally investigated as part of this study. Internal and external overvoltages caused by short-circuit faults or circuit opening/closing in the generation, transmission and distribution lines cause voltage/current oscillations on the lines at different frequencies. At frequencies of 50, 150, 250, 350, and 500 Hz in different electrode systems such as Sphere-Plane and Needle-Plane, the effects of these oscillations at various frequencies in the networks on the ignition and damping of corona discharges on transmission lines have been investigated. The results showed that the ignition and damping voltages of corona discharges are greatly influenced by high-frequency voltage/current oscillations, and that an increase in the frequency value significantly speeds up the corona discharge’s ignition.
