Abstract

The magnitudes and waveforms of overvoltages produced by the energisation operation of a transmission line depend, among other factors, on the source-side circuit configuration, line trapped charge, and pre-insertion resisters. This paper investigates the effects of these three factors in case of steep fronts and severe spikes appear in the overvoltage waveform obtained at the remote end of the energized line. Computer study is reported and the results show that the steep fronts and spikes are largest when trapped charge is present.
