Answer Posted / rajneesh upadhyay
OLTC means on load tap changer .
By this we can regulate the voltage level of load side
which is always varying but must be constant .
By this we can change the no of turns of hv side so turn
ratio hence voltage level of load side on loaded condion.
tap changing coil is placed over hv and connected to hv to
accurate voltage variation .

ii) A shunt motor supplied at 230V, runs at 900 rpm when the current is 30A. The resistance of the armature is 0.4 ohms. Calculate the resistance required in series with the armature to reduce the speed to 600 rpm, assuming that the armature current is then 20A. [12]
