What is the relation of the secondary winding leakage reactance and secondary circuit in impedance?

Clarification: The secondary winding leakage reactance is directly proportional to the secondary circuit impedance. In secondary winding the leakage reactance is reduced and in turn the secondary circuit impedance is reduced.

Why flux in primary and secondary winding is always equal?

flux produced in primary winding will pass through the secondary winding, so generated flux in primary winding will be same as in secondary winding. Flux, low Reluctance path provided by iron core, and both side iron core is similar therefore flux on both sides is equal.

What is leakage flux in alternator?

The Magnetic Leakage Flux in Induction Motor is that flux which links only the stator or only the rotor windings. Because of the presence of air-gap in the magnetic circuit of machines, the leakage in these is quite significant and cannot be neglected in analysis as could be done in the case of transformers.

What is the effect of load on leakage flux in transformer?

This φL2 is in time phase with I2 and produces a self-induced e.m.f eL2 in the secondary winding. The both leakage flux at primary and secondary fully depends on the load of the transformer. If load of transformer increase, leakage flux will simultaneously increase.

Why does leakage flux not transfer energy from primary winding to secondary?

This leakage flux does not link with both the windings, and hence it does not contribute to transfer of energy from primary winding to secondary winding. But, it produces self induced emf in each winding. Hence, leakage flux produces an effect equivalent to an inductive coil in series with each winding.

What is meant by leakage reactance of transformer?

Due to this leakage flux in transformer, there will be a self-reactance in the concerned winding. This self-reactance of transformer is alternatively known as leakage reactance of transformer. This self-reactance associated with resistance of transformer is impedance.

What is the leakage flux of a magnetic circuit?

This leakage flux φL1 completes the magnetic circuit in the portion ( a-b ) .Hence, this flux is known as primary leakage flux and is proportional to the primary ampere-turns. This flux φL1 is in time phase with primary current I1 and induces an e.m.f eL1 in primary winding only.
