Real-time monitoring traces of Sulfr hexafluoride in near-source ambient air

The leakage of sulphur hexafluoride (SF 6) gas threats the global climate changes and personnel safety. Monitoring the concentration of SF 6 in its application places is an industry regulation. In this study, ion mobility spectrometry (IMS) was developed for fast monitoring traces of SF 6 in near-source ambient air.Get price

First insulating gas-free voltage transformers for 420 kV | References

Worldwide, many TSOs intend to eliminate greenhouse gases for new installations of gas-insulated equipment and therefore continue to contribute to their voluntary self-commitment in SF 6 reduction. Until now, SF 6 -free voltage transformers were available for voltages up to 245 kV. Recently, Siemens has succeeded to expand the blue portfolio, which exists of a broad spectrum of CO 2 equivalent-free equipment for air-insulated and gas-insulated switchgear, with a 420 kV voltage transformer.Get price
