| Abstract: | The 50 Hz AC insulation characteristics of c-C4F8 and CF4 hybrid gas in extremely non-uniform electric fields are studied through experiments to find out the optimal hybrid ratio,air pressure,and electrode distance.The results show that the hybrid gas is in its best insulation state with the hybrid ratio of 5%,20 mm electrode distance,and 0.3 MPa pressure. |
