Answer Posted / atif rasheed khan
there are two cases arises here, in first case our answer
will be yes under the following condition.
the generator should be so excited till its voltages
produced be equal to the previous step up voltages done
through transformer, however these rise in voltages are just
restricted to 33KV, because beyond this voltage level there
arises a critical issue of the winding insulation.
in this method just reverse the connections, i-e change the
L.T as sending voltage side, and the H.T as generation side.
however in the second case , our answer will be no, if
higher voltage step up transformer are used, due to the
above mentioned problem of insulation of transformer.

A 50Hz,4-pole,3-phase,star-connected synchronous motor has a synchronous reactance of 12ohmsper phase and negligible armature resistances.the excitation is such as to give an open-circuit voltage of 13.2kilovolt.the motor is connected to 115kilovolt, 50hertz supplying. what maximum load can be the motor torque,line current and power factor?

Give me the calculation steps to design an electromagnet to be work in 230V 50 Hz AC Supply. Also give force that is created by that electromagnet when it gets energized.
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]
