Abstract

The authors proposed a simple electric model to simulate the windings used in gas-insulated shunt reactors up to a high frequency range. Its applicability was evaluated by comparison with measurements of the full-scale apparatus model. The impedance of the high frequency electric model is well simulated over a frequency range of several kHz to 10 MHz. In this paper, the proposed high frequency electric model was used for analysis of the re-ignition surges at interruptions of the reactor of a model substation. The analysis waveform gave a faster rise and lower peak value than those of the low frequency electric model, and the cause was clarified
