Myth About insulating gas Gas In Electrical Equipment

Apr 12, 2021 · Buildings containing Sulfr hexafluoride-filled indoor equipment should be provided with ventilation; natural ventilation would normally be adequate to prevent the accumulation of Sulfr hexafluoride released due to leakage (see IEC 61634, sub-clause 3.4: “Safety of personnel” and IEC 61936-1).
