current chopping in CB is the incident of arc current
interruption before normal current zero is reached.If This
current is enough to deliver a voltage which is greater than
restriking voltage then the arc will continue again. But
gradually the current falls and certainly the voltage also
reduces and finally fall down the restriking voltage and
ultimately arc is extinguished. It results in voltage
oscillation in the line which affects the electrical
equipments.
