ne power station has rotor of small diameter and high length other than that used in hydrop

D2. When a generator's full-load output voltage is the same as its no-load output voltage it is said to be a) under-compounded b) flat-compounded c) over-compounded d) none of the above D3. The output of an overcompounded DC generator can be lowered by use of a a) rheostat connected in series with the series field b) rheostat connected in parallel with the series field c) rheostat connected in parallel with the shunt field d) none of the above D4. When might it be desirable to use an overcompounded generator? a) never b) always c) to compensate for line loss d) when you need a higher no-load voltage than your full-load voltage

A synchronous generator runs at 250 rpm and generates at 50-Hz. There are 216 slots, each containing 5 conductors arranged in a full-pitched winding for 3-phase star connection. All the conductors of each phase are in series and the flux per pole at no-load sinusoidally distributed over the pole pitch is 30 mWb. Find the emf induced in each phase winding and the terminal voltage.

Please solve , last time i got wrong answer

A 4 pole dc generator with duplex wave winding has 48 slots and four elements per slot. The flux perpole is 2.5 x 10 Maxwells and the speed of the prime mover is 30 rpm. What is the average generatedarmature voltage? Neglecting brush drop.

2A. What is another term for "shunt"? a) in series b) in parallel c) compounded d) none of the above 2B. Which of the following is/are a basic type of DC generator connection? a) series b) shunt c) compound d) all of the above

please help how to know if they are given terminal voltage or phase voltate. what is the difference between both and the answer would change?

1. Complete the following sentence: A three-phase synchronous generator consists of three electromagnets located at 120 degrees from each other that induce voltages i the rotor windings is a rotating electromagnet that induces voltages in the three stator windings functions in the same way as an asynchronous generator. is equivalent to an eddy-current brake.

A single phase, 2000 V alternator has armature resistance and reactance of 0.8 ohms and 4.94 ohms respectively. The voltage regulation of the alternator at 100 A load at 0.8 leading power factor is ??

There are 160 slots in a 3-phase, 8-pole, 50 Hz., star connected alternator. There are 4 conductors in each slot and all the conductors in a phase are connected in series. Coil span is 150° electrical and the flux per pole is 0.08 Weber sinusoidally distributed. Calculate the emf induced per phase.
