so2 solution for HV MV

so2 solution for HV MV

Abstract. Sulphur hexafluoride (SF6) is a synthetic gas extensively used in the high voltage (HV) electricity transmission and distribution industry. The unique and unrivalled properties of SF6 gas that enable it to resist/recover from spark conduction have positioned it as the preferred HV arc interruption medium.

  • SF6 properties, and use in MV and HV switchgear

    2020-1-29– HV – and Extra High Voltage – EHV. At Merlin Gerin, the research work, concerning the use of SF 6 gas for insulation and circuit-breaking was initiated around 1955. This coïncides with the appearence of the first industrial products in the U.S. The first industrial applications from Merlin Gerin were at EHV, then in Medium Voltage –MV
