Abstract
This paper investigates the influence of some parameters on the magnitude of the transient overvoltages after disconnector restrike. In case of open-ended GIS the transient overvoltage consists of rectangular pulses due to strictly odd-numbered harmonics. In case of lumped capacitances in the GIS this strict order within the harmonics is changed, which results in higher overvoltages. A large capacitor to ground was found to yield the highest overvoltages.
