sf6 gas insulated switchgear gas leak detector for abb

ObjectiveProblemMethodThe objectives of this project are to: 1. Conduct a literature review on all previous research considering SF6 gas alternatives; 2. Identify alternative solutions from the literature review which can be recommended for initial testing; 3. Conduct initial interruption and insulation tests on the proposed gases and document outcomes; and 4. Disseminate the lessons learnt to internal and external stakeholders.See more on westernpower.co.ukEssentials of SF6 monitoringTD Guardian Articles ... SF6 has a global warming potential that is almost 24,000 times greater than CO2, it gets a lot of attention. And since the electric power industry is responsible for nearly 80% of the world's usage, our industry has taken significant steps to reduce or eliminate the emissions from gas insulated switchgear.
