摘要

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