  • Myth About Sulfr hexafluoride 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 gaz sf6 released due to leakage (see IEC 61634, sub-clause 3.4: “Safety of personnel” and IEC 61936-1). Type and extent of required measures depend upon location of the room, the accessibility, and the ratio of gas to room volume.

If you ground the HV, you cannot measure the condition of the HV to ground insulation or the HV to LV, since everything is now LV to ground. And the HV to ground and to LV are probably your more critical measurements (at 500kV!).
