SF6-alternatives leak check for Mitsubishi

SF6-alternatives leak check for Mitsubishi

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.ukSF6 ALTERNATIVE – WHAT TO LEARN FROM THE detection and gas quality check The integral tightness test was performed in the factory using dedicated measuring equipment with the evaluation of the fluoronitrile and CO 2 losses (Fig. 4). On site, the tightness was checked using standard sf6 leak seekers which were qualified for the CO 2 and fluoronitrile detection [8].

    Tracer gas leak testing is a simple and highly-efficient method of leak detection that provides high sensitivity, accuracy, and repeatability. A tracer gas leak test can be used to test parts with very low leak rates that are outside the range for conventional air-flow pressure decay and mass flow testing, or to replace bubble test methods.
