sf6 emissions Grid Solutions for extra high Voltages

SF6 does not constitute a major part of Fingrid's carbon footprint. The greatest impact is made by transmission losses, which gave rise to emissions of 200,400 CO2eq in 2018. A Europe-wide solution. In the European Union, emissions of SF6 gas are equivalent to 6.73 million tonnes of carbon dioxide, which is about 0.15 per cent of total emissions.

    SF6 circuit breakers suffer less wear on the main contacts than do air and oil circuit breakers. The breaking principle is to cool down the arc by blowing SF6 gas with high pressure towards the arcing contacts. An SF6 circuit breaker’s arc extinction method may be characterized as either puffer or self-blast.
