Guidelines for SF6 end-of-life treatment of T&D equipment (>1 kV) in substations

Electrical equipment using SF6 as insulating and/or arc quenching gas is widely used globally since the second half of last century. Due to its superior technical performance, SF6 technology has been implement-ed in applications for medium voltage (MV, ≤52 kV) in distribution network, high voltage (HV, >52 kV) in bulk power generation and transmission, and all the way up to ultra-high voltage (1200 kV).
