SF6-alternatives training Hi-pot

At the time of production, SF6 gas circuit breakers are subject to a high-voltage withstand test. This incorporates an AC High-Potential (Hi-Pot) test transformer capable of achieving the required high-voltage levels (per industry standards). Therefore, field Hi-Pot testing is also not necessary or required.

  • Western Power Distribution - SF6 Alternatives

    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.

    The vacuum level in the bottle can be checked by performing a hi-pot test on the bottle per the manufacturer’s instructions. Vacuum circuit breakers and contactors have fewer components and lower operating forces than other types.

  • Putting Hipot Out to Pasture | ECM

    As DC high-potential testing starts to show its age, test methods recommended by IEEE are ready to fill the void For many years, high-voltage DC testing has been the traditionally accepted method to judge the serviceability of medium-voltage cables. DC high-potential (hipot) tests worked well as a withstand and condition assessment test for paper- and oil-insulated, lead-covered (PILC) cable. Even
