SF6-filled Measurement CHINT

SF6-filled Measurement Quantitative. 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).
