2016-9-9A Circuit breaker is a device that interrupts the abnormal or fault currents and in addition performs the function of a switch. Circuit breakers are essential for circuits operating at higher voltages and equipment that carry large currents. For voltages higher than 3.3 KV isolation is provided by circuit breakers.

SF6 Gas Emissions With growing concerns on our planet’s greenhouse gas emissions, many utilities are looking to eliminate or reduce their contribution to SF6 emissions. For systems with high fault potential, where power fuses are not appropriate, the use of SF6 gas is still the primary arc extinguishing medium used in transformer

Currently, there are no available substitutes for SF6 in high voltage applications. Fugitive emissions of SF6 can escape from gas-insulated substations and switch gear through seals, especially from older equipment. The gas can also be released during equipment manufacturing, installation, servicing, and disposal.
