Gas Insulated Switchgear

Over the past decades, Gas-Insulated Switchgear (GIS) or circuit-breaker using SF₆ (sulfur hexafluoride) as dielectric and arc-quenching medium have gained a significant market share in the T&D industry, with an increased capacity of high-voltage T&D nodes in dense urban areas.

However, because SF₆ is also one of the most potent greenhouse gas (its global warming potential is more than 22,000 times stronger than CO₂), the main industry stakeholders in GIS solutions, manufacturers, and operators have proactively and continuously innovated to minimize the SF₆ emissions since the Kyoto Protocol was accepted in 1997.

Beyond the environment protection objective, achieving excellence in the equipment tightness is critical to meet the highest standards in reliability and availability of critical power grid assets.

LumaSense Technologies’ Gas Solutions contribute to this global effort and are recognized as state-of-the-art and reliable leak detection instrument.
