Environmental ImpactReducing DowntimeHigh-End Optical Gas Imagersf 6 is over 23,000 times as potent as carbon dioxide as a greenhouse gas, so SSEPD wants to make sure that sf6 gas assets are carefully managed. "We take our safety and environmental responsibilities very seriously, with regular maintenance and protection of equipment. We have a very large fleet of switchgear and we work constantly to ensure its safe operation," comments Tawanda Chitifa, Project Manager at SSEPD. As part of an internal R&D project, we investigated ways to improve our environmental impact. The challenge was to be more efficient in handling possible Sulfr hexafluoride leaks. Thermal imaging cameras from FLIR have helped us reduce that risk, because they allow us to detect possible leaks quickly and with high certainty.” Clearly pinpoint leaks Conventional leak detection methods include the use of sniffers.
