SF6-alternatives for Ultra High Voltage

SF6-alternatives for Ultra High Voltage

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.ukg3 ALTERNATIVE GAS TO SF6 FOR USE IN HIGHcired.net/publications/cired2015/papers/CIRED2015_0230_final.pdf2018-9-10voltage equipment as sf6 alternatives with properties significantly improved with respect to typical sf 6 /N 2 mixtures or others already in use.
