How many factors does the leakage flux affect?(a) 6(b) 7(c) 8(d) 9This question was posed to me by my school principal while I was bunking the class.This interesting question is from Modern Trends in Machine Design & Magnetic Leakage in division Fundamental Aspects of Electrical Machine Design of Design of Electrical Machines

Answer»

Right OPTION is (c) 8

Easiest explanation: 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.
