It can be oper ted manually or automatically. The automatic operation needs a separate mechanism which consists of a trip coil. The trip coil is energized by se
rate of change of current dI.Thus the function of the circuit breaker is to raise the arc characteristics w thout affecting its stability. This is done by reducing the arcing time which is the time from contact separat on to final extinction of arc. But it wi l increase extinction voltage. Hence compromise between arcing time and
the circuit breaker contacts. This process is known as Resistance Switching. When the rtsistance is connected across the arc, a part of the arc curren flows through the resistance. This will lead to decrease in arc current and increase in rate of deionization of the re path and resistance of arc. This will increase cur
