SF6 room Grid Solutions for high voltages

Myth About SF6 Gas In Electrical Equipment. May 25, 2020Buildings containing SF6-filled indoor equipment should be provided with ventilation; natural ventilation would normally be adequate to prevent the accumulation of SF6 released due to leakage (see IEC 61634, sub-clause 3.4: "Safety of personnel" and IEC 61936-1).
