The ammeter reading gives the primary equivalent of full load current I L. As the voltage applied for full load current in short circuit test on transformer is quite small compared to the rated primary voltage of the transformer, the iron losses in the transformer can be taken as negligible here.
In electrical engineering, a transformer is a passive component that transfers electrical energy from one electrical circuit to another circuit, or multiple circuits.A varying current in any coil of the transformer produces a varying magnetic flux in the transformer's core, which induces a varying electromotive force (EMF) across any other coils wound around the same core.
Secondary leakage reactance X S, referred to the primary circuit by the turns ratio squared; Equivalent core loss resistance R C and core loss current I C; Magnetising reactance X M and magnetising current I M; No-load current I 0; Primary and secondary EMF E P and E S, developed over an ideal transformer

A circuit that behaves like a snap-action switch, suddenly changing state as an analog signal increases; displays hysteresis. Schottky diode A diode that relies on the junction between a semiconductor and a metal. Scott-T transformer A transformer connection for balanced interconnection of a two-phase system and a three-phase system. s-domain
The power input to the transformer and output from the transformer is the same (except for conversion losses). The side with the lower voltage is at low impedance (because this has the lower number of turns), and the side with the higher voltage is at a higher impedance (as it has more turns in its coil).
Darlington gives an equivalent transform that can eliminate an ideal transformer altogether. This technique requires that the transformer is next to (or capable of being moved next to) an "L" network of same-kind impedances. The transform in all variants results in the "L" network facing the opposite way, that is, topologically mirrored. [2]
Often, an equivalent circuit is sought that simplifies calculation, and more broadly, that is a simplest form of a more complex circuit in order to aid analysis. [1] In its most common form, an equivalent circuit is made up of linear, passive elements. However, more complex equivalent circuits are used that approximate the nonlinear behavior of ...
