That's why most (if not all) breakers that have these coils also have a switch inside to de-energize the coil once the breaker has tripped. Even if the breaker didn't have such a switch, if the shunt trip control circuit is powered ... WebExpert Answer. b) The following table provides the data for the O.C. test of a DC shunt generator at 300rmm. Plot the O.C.C. for 375rpm and determine the voltage to which the machine will excite if field circuit resistance is 40Ω. i) Calculate the additional resistance to be inserted to the field coil to reduce the voltage to 200 V at 375rpm ?
