SF6 Gas re-use for Substation

SF6 Gas re-use for Substation

SF6 gas is strongly electronegative, which means the free electrons are easily removed from discharge by the formation of negative ions. Now a day puffer piston pressure is used for generating arc quenching pressure during an opening operation by mean of a piston attached to the moving contacts.
