要約(日本語): SF6 alternative gas mixtures using C4-FN, C5-FK, CF3I and HFO1234zeE which has similar or higher dielectric strength and lower GWP compared with SF6, have been investigated for insulation media of GIS along with natural gases like CO2, N2 or dry air. In this study, the authors focused on C4-FN, C5-FK, CF3I and HFO1234zeE gases as the EN gas, and N2 and CO2 gases as the buffer gas, and investigated the dielectric performance of these gas mixtures based on the reduced critical field strength（E/N）crit as well as the synergy effect using the synergism coefficient “S”.
