  • Panel discussion: The pros and cons of using SF6

    10 mins readJul 14, 2015Oil circuit breakers came as a panacea to reduce the footprint of air circuit breakers. However, even though they offered a huge reduction of footprint, they are maintenance intensive and require the changing of oil after some operations. Additionally, oil based circuit breakers are not very safe to operate because of the fire risk.
