The present paper reports fundamental properties of CF 3 I under high‐temperature conditions to find out the usefulness of CF 3 I as an arc‐quenching gas. Firstly, particle compositions of CF 3 I were theoretically calculated in a temperature range from 300 to 30 000 K. Secondly, thermodynamic, transport and radiation properties of the CF 3 I were also obtained for pressures 0.1–1.0 MPa. Finally, the transient process of a conductance of a residual arc in CF 3 I was derived to compare with those in other arc‐quenching gases. In addition, an arc extinguishing capability of CF 3 I in a thermal re‐ignition region was derived to find out whether CF 3 I shows a higher capability than CO 2 , N 2 and air. © 2006 Institute of Electrical Engineers of Japan.
