CEA panel outlines phased shift away from SFâ in substations
The Central Electricity Authority (CEA) has released a committee report recommending a phased transition away from sulphur hexafluoride (SFâ) gas in high-voltage substations, citing its high greenhouse impact and emerging global restrictions. The report, published by a six-member technical committee under the Ministry of Power, evaluates alternatives under âGreen GISâ technologies that replace SFâ with lower-emission insulating media. SFâ has long been used in gas-insulated substations (GIS) due to its strong dielectric and arc-quenching properties….
