Meaning of Current Chopping and in Circuit Breaker

The current chopping circuit breaker is forcely classified into the natural current and before the force of current is placed in the current chopping.It is mainly used in the vacuum circuit breaker because of Air blast circuit breaker is mainly consumed during the pumping of air in circuit conductor.The oil will put into the vacuum cleaner and because of dominant shunt resistor is called current chopping.

Current chopping:

The current chopping is defined as the extinction of placed in the natural current is zero.The capacity of circuit breaker is controls the air pumping and system of level in current.The natural current is always zero.

The air buster and air blast circuit breaker is used by the clearing capacity and the fixed value of before natural current is always zero.

Let us saw the shunt reactor diagram in the following

Current Chopping and in Circuit Breaker

The above diagram represented the L,C,R

L-shunt reactor.

C-Capacitance

R-Reactor

The shunt reactor is always takes place in the magnetizing current. during normal condition current flowing through the reactor is I and hence the magnetic energy is become zero.

It follows the reaction in mathematics

LI2 / 2 = CV2 / 2

Here V = Voltage across the capacitor

Thus, V = I √(L/C)

The current chopping is always come into play the capacitor in the system.the high voltage resistor will directly proportional to the reactor.

To carefully observe the figure and current chopping will reduce the magnitude of current.
