In this paper, we propose a circuit model of gas‐insulated shunt reactors for surge analyses in high‐frequency regions. The interleaved disk winding, widely used for high‐voltage windings, has resonance phenomena in the high‐frequency region and its series capacitance decreases above the resonant frequency. In order to simulate this phenomenon, an equivalent circuit composed of three‐stage LC parallel circuits was proposed. On the contrary, the continuous disk winding can be simulated by one‐stage LC parallel circuit because its series capacitance is almost constant through to the high‐frequency region. Impedance characteristics of a full‐scale model for a reactor winding were measured and the proposed circuit model was evaluated by comparing the measured results with the calculated ones. It was verified that the proposed model could represent well the winding impedance up to 10 MHz. © 1998 Scripta Technica, Electr Eng Jpn, 123(2): 32–39, 1998
