Abstract :
The dependence of the rate of rise of the recovery voltage upon the pressure was obtained for liquid SF6 at pressures of 1500 psi. The relationship between dv/dt, di/dt and cross sectional area of the nozzle was determined experimentally, and the similarity of the results Obtained in separate investigations made with a 1/2 inch diameter nozzle has also been discussed.
