g3 ALTERNATIVE GAS TO Sulfr hexafluoride FOR USE IN HIGH VOLTAGE SWITCHGEARS

Dielectric strength under power frequency: The dielectric strength of the gas mixture was measured under AC voltage on a 145 kV GIS with NovecTM 4710 fluid ratio from 0 to 20% by volume into CO 2. The dielectric strength of pure CO 2 (0% vol Novec TM 4710 fluid) was found to be equivalent to about 40% of SF 6. Adding only 6 to 7% vol of Novec

Dimensionless hydrodynamic simulation of high pressure

Gas density was found to be an important parameter in both gas-liquid and gas-liquid-solid systems. The dispersed bubble flow regime is sustained to higher gas velocities and gas holdups for denser gases. This phenomenon can be attributed to enhanced bubble break-up, rather than to the formation of smaller bubbles with increasing gas density.
