Sulphur Hexaflouride (SF6) Management Strategy in Transgrid’s HV Transmission Network

SF6 plays an integral role within Transgrid’s high voltage (HV) transmission network due to its efficient electrical insulation properties at up to 500kV. Along with its dielectric properties, SF6 is excellent for arc-quenching, is non-flammable, and non-toxic making it the preferred insulating gas used in HV electrical equipment ensuring its safe and reliable operation. Despite the beneficial properties of SF6 for electrical equipment, the global warming potential
