Answer: c
See lessExplanation: There are 8 factors which are affected by the leakage flux. They are
performance of rotating machines and transformers, excitation demands of salient pole machines, leakage reactance of windings, forces between windings, voltage regulation of ac generator and transformers, commutation condition in dc machines, stray load losses, circulating current in transformer tank walls.
What is the function of the leakage flux?
Answer: d Explanation: The leakage flux produced due to the low reluctance path does not transfer the energy produced. The leakage flux also does not convert the energy in the system.
Answer: d
See lessExplanation: The leakage flux produced due to the low reluctance path does not transfer
the energy produced. The leakage flux also does not convert the energy in the system.
How should the air gaps be present in the magnetic circuit according to length and cross section?
Answer: d Explanation: The air gaps should be present in the magnetic circuit in the low length. The air gap should have maximum cross section to reduce the reluctance.
Answer: d
See lessExplanation: The air gaps should be present in the magnetic circuit in the low length.
The air gap should have maximum cross section to reduce the reluctance.
What is the relation between reluctance, flux and mmf of the machine?
Answer: a Explanation: The designer’s problem is to provide a path of low reluctance to that of comparatively little flux leaks away. In order to compensate for the flux leakage, high mmf is maintained.
Answer: a
See lessExplanation: The designer’s problem is to provide a path of low reluctance to that of
comparatively little flux leaks away. In order to compensate for the flux leakage, high
mmf is maintained.
