why exterrnal C.T. protection is used even though ACB& VCB
is having inbuild C.T. protection?

Answer / k.prakashchandra
In-built protection is for currents exceeding the rated
current of the breaker,which is usually higher than that of
your requirement.Further, you can not alter this unless you
replace the cts.
