Transformer Reflected Inductance

The reflected and shunt impedances in equivalent circuits transformers a transformer is a mutual inductor. Faradays law tells us that a changing magnetic flux will induce an emf in a coil.

The induced emf for a coil with n loops is.

Transformer reflected inductance. A device that transfers electrical energy between electrically isolated circuits by using the magnetic field associated with current. Transformer leakage reactance has a large role in limiting circuit fault current within the maximum allowable value in the power system. Self inductance and magnetic energy.

Both the primary and secondary windings of a real transformer exhibit electrical resistance due to copper losses and inductance due to magnetic flux leakage. In these cases the leakage inductance limits the current flow to the desired magnitude.

The term is slightly ambiguous or perhaps usage varies from one field of application to another. The property describing the effect of one conductor on itself is more precisely called self inductance and the properties describing the effects of one conductor with changing current on nearby conductors is called mutual inductance. Reflected impedance an output transformer has no impedance by itself ignoring primary inductanceresistance for the moment which is a different subject.

Transformers with variable leakage inductance are used to control the current in arc welding sets. As modeled in our initial example the powered inductor of a transformer is called the primary winding while the unpowered coil is called the secondary winding. It simply reflects the impedance load on the secondary back to the primary.

The self inductance of a transformer is the net inductive effect reflected onto the primary circuit by the transformer windings. In transformers the inductor coils are often referred to as windings in reference to the manufacturing process where the wire is wound around the core material. This is the principle behind a transformer.
