2. Purity expressed in % of SF 6 in the gas sample tested 3. Decomposition products, usually measure by SO2 detection Typical values for above are: 1. Moisture: <50 ppmv for new gas, <150ppmv for gas in use in a breaker or GIS and 150ppmv is wet gas that needed drying or re-conditioning and 400ppmv is definitely dangerous to use. 2.

Vacuum Pressure Impregnation and Process

Vacuum Pressure Impregnation (VPI) You’ve probably heard that vacuum pressure impregnation (VPI) is a good alternative to the old “dip and bake” varnish process, but there’s actually a bit more to it than that. While VPI offers excellent benefits for smaller electric motors, it may not always be the best choice for larger ones.
