During circuit breaking operation, the cylinder moves downward against the piston to break the connection between the fastened contacts. Consequently, it reduces the quantity inside the cylinder, compressing the SF6 inside it. The metallic separation inside the arc chute acts as an arc separator and it divides the arc into small arcs that increase the voltage required to keep up the arc. As quickly as the primary contacts open up, the current will flow via the arcing contacts. The arc sweeps upwards leading to coo
