SF6 is a gas commonly used in the power industry to provide electrical insulation and arc interruption. However, SF6 is a potent greenhouse gas with a global warming potential that is 25,200 times greater than CO2†.
The £1.9m project will see experts at Manchester help determine how National Grid can develop a retrofill solution to replace SF6 with an environmentally friendlier alternative without having to replace or otherwise modify the existing equipment.
