  • Panel discussion: The pros and cons of using SF6

    10 mins readJul 14, 2015As the quantities that leak from the switchgear are low, the contribution to the greenhouse effect can be considered extremely minimal to affect climate changes. Nevertheless, there are toxic by-products that are produced in SF 6 during arcing. Hence SF 6 leakages can become dangerous when leaked in large concentrations. However, if leaks
