Question 12

A three phase synchronous generator is to be connected to the infinite bus. The lamps are connect ed as shown i n t he fi gur e for t he synchronization. The phase sequence of bus voltage is R- Y- B and that of incoming generator voltage is R' - Y' - B'. A 3 phase, 50 Hz, six pole induction motor has a rotor resistance of 0.1 and reactance of 0.92 . Neglect the voltage drop in stator and assume that the rotor resistance is constant. Given that the full load slip is 3%, the ratio of maximum torque to full load torque is?

Question 13

For a specified input voltage and frequency, if the equivalent radius of the core of a transformer is reduced by half, the factor by which the number of turns in the primary should change to maintain the same no load current is, A three-winding transformer is connected to an AC voltage source as shown in the figure. The number of turns are as follows : N1= 100, N2= 50. If the magnetizing current is neglected, and the currents in two windings areI2= 2 30 A andI3= 2 150 A, then what is the value of the currentI1in Ampere?

Question 14

A 3-phase transformer rated for 33 kV/11 kV is connected in delta/star as shown in figure. The current transformers (CTs) on low and high voltage sides have a ratio of 500 / 5. Find the currents i1and i2, if the fault current is 300A as shown in figure. A balanced (positive sequence) three-phase AC voltage source is connected to a balanced, start connected through a star-delta transformer as shown in the figure. The line-to-line voltage rating is 230 V on the star side, and 115 V on the delta side. If the magnetizing current is neglected andIs= 100 0 A, then what is the value ofIpin Ampere?

Question 15

A 4-pole, separately excited, wave wound DC machine with negligible armature resistance is rated for 230 V and 5 kW at a speed of 1200 rpm. If the same armature coils are reconnected to forms a lap winding, what is the rated voltage (in volt s) and power (in kW) respectively at 1200 rpm of the reconnected machine if the field circuit is left unchanged , The synchronous generator shown in the figure is supplying active power to an infinite bus via two short, lossless transmission lines, and is initially in steady state. The mechanical power input to the generator and the voltage magnitude E are constant. If one line is tripped at time t1by opening the circuit breakers at the two ends (although there is no fault), then it is seen that the generator undergoes a stable transient. Which one of the following waveforms of the rotor angle shows the transient correctly?r
