Abstract: Although the contribution of SF6 (sulfur hexafluoride) emissions from gas insulated medium-voltage switchgear to man-made global warming is very small, an eco-efficient insulation gas will contribute to a reduction in the carbon footprint of the electricity grid. Each tank has a safety valve which can be opened to remove the pressure increase caused by internal arc. In order to keep proper isolation of bolted connections in the feeder bays of the TPM P system switchgear, an RCAB or 15TS/NSS type adapter should be additionally installed, according to the cable bushing used (details in DTR switchgear TPM type). A permanent process of improvement has led to today’s 8DQ1.
