In a previous paper breakdown strengths of c-C/sub 4/F/sub 8//SF/sub 6//CO gas mixtures in various proportions were reported for a 30mm rod-sphere gap under ac and impulse voltages. A mixture of 1% c-C/sub 4/F/sub 8/ + 59% SF/sub 6/ + 40% CO exhibited higher dielectric strength than pure SF/sub 6/ in the pressure range between 350 and 400 kPa. The present paper compares CO and N/sub 2/ as a buffer in gas mixtures and extends the studies to a nearly uniform field gap and a highly non-uniform field gap. Additional experiments confirmed that the use of CO as a buffer in gas mixtures is superior to N/sub 2/ and that some c-C/sub 4/-F/sub 8//SF/sub 6//CO gas mixtures have higher dielectric strength and are cheaper than pure SF/sub 6/.
