Green Gas for Grid - g3 - SF6 Free Solutions 6 SF6 (or Sulphur Hexafluoride) had been the standard gas used inside high voltage electrical equipment as an insulating and arc-quenching medium. However, SF 6 SF6 is also listed as an extremely potent greenhouse gas according to the Kyoto protocol, with 23,500 times the comparative Global Warming Potential of CO 2 and a lifetime of 3,200 years in the atmosphere.[email protected]
Dry Type Transformers Explained | The Electricity Forum Type Transformers "transform" voltage either up to a higher voltage (step up) or down (step down) to a lower voltage. Normally, that transformation takes place when power line transmission voltages (such as 500 kV) are "stepped down" to a much lower level, suitable for use by iindustrial power systems (30 kV) aor residential (120-240V).Get Price
