What is mutual flux in transformer?

Mutual inductance is where the magnetic flux of two or more inductors are “linked” so that voltage is induced in one coil proportional to the rate-of-change of current in another. A transformer is a device made of two or more inductors, one of which is powered by AC, inducing an AC voltage across the second inductor.

In this regard, what is a leakage transformer?

Leakage Transformers are transformers where the magnetic flux of the secondary is loosely coupled to the flux of the primary. This loose coupling ensures that the transformer can withstand short circuit conditions.

What is the meaning of transformer impedance?

Definition. The percentage impedance of a transformer is the volt drop on full load due to the winding resistance and leakage reactance expressed as a percentage of the rated voltage. It is also the percentage of the normal terminal voltage required to circulate full-load current under short circuit conditions.

What is meant by fringing flux?

Flux fringing - a phenomenon in which the magnetic flux flowing in a magnetic core spreads out (or fringes out) into the surrounding medium, for example in the vicinity of an air gap. Flux crowding is closely related to flux fringing, but flux leakage is usually treated as a different phenomenon.
