Equivalent Circuit Diagram Of Transformer. Hence the function of windings thereafter will only be the transforming the voltage. In the above circuit diagram the primary current of the transformer serves two components i o and i 2 the no load current i o also known as the magnetizing current which produces flux and magnetizes the core with losses in the core.
The expressions for these components are as follows. Equivalent circuit of a transformer is a schematic representation of a practical transformer that shows all electrical parameters such as winding resistance reactance admittance susceptance primary and secondary voltages currents etc. Hence the function of windings thereafter will only be the transforming the voltage.
Equivalent circuit of a transformer having transformation ratio k e 2 e 1 is shown in fig.
I µ magnetizing component i w working component this i µ i w are connected in parallel across the primary circuit. This voltage causes iron loss current i 0 and magnetising current i m and we can therefore represent these two components of no load current by the current drawn by a non inductive resistance r 0. I µ magnetizing component i w working component this i µ i w are connected in parallel across the primary circuit. In the above circuit diagram the primary current of the transformer serves two components i o and i 2 the no load current i o also known as the magnetizing current which produces flux and magnetizes the core with losses in the core.
