This month’s Featured Technical Paper is from the Proceedings of the 2019 International Conference of Doble Clients. The paper is titled: SF6 – The Alternative Gas
With the ever-growing challenges of federal & local reporting and SF6 emission reduction, a number of alternatives have been presented to the industry in replacement of SF6 gas. As the industry continues to review and consider alternatives, we should not limit our solutions. SF6 continues to be the best alternative for medium and high voltage electrical insulation and arc quenching in gas insulated equipment (GIE). Turning to the existing stockpile of SF6 gas offers an environmentally friendly alternative solution to importing virgin SF6 gas from overseas. The implementation of reconditioned SF6, which has been properly treated to meet or surpass IEEE, IEC and CIGRE standards, helps to reduce the carbon footprint and eliminates SF6 emissions that are the direct result of the manufacturing process. Awareness and preventative measures will allow our industry to continue using this insulating medium safely, provided the benefits of reuse are shared and understood.
