Simplified Equivalent Circuit of a Transformer
SIMPLIFIED EQUIVALENT CIRCUIT: While drawing simplified circuit of a transformer, the exciting circuit (i.e., exciting resistance and exciting reactance) can be omitted. The simplified equivalent...

Why are iron losses constant at all loads in a transformer?
Since the induced primary ampere-turns and secondary ampere-turns always neutralise one another, the flux in the core on load is the same as the flux...
Why do we represent leakage flux in a transformer by inductive reactance?
In an actual transformer, there is primary leakage flux as well as secondary leakage flux. The primary leakage flux is the flux which links with...
Applications of Transformer
Main applications of the transformers are given below: To change the level of voltage and current in electric power systems. As impedance-matching device for maximum...
Mutual and Leakage Fluxes of a Transformer.
MUTUAL AND LEAKAGE FLUXES: So far, it is assumed that when AC supply is given to the primary winding of a transformer, an alternating flux...
COMPARISION BETWEEN CORE-TYPE AND SHELL-TYPE TRANSFORMER.
COMPARISION BETWEEN CORE-TYPE AND SHELL-TYPE TRANSFORMER: Sr. No. Core-type transformer Shell-type transformer 1. The windings surround a considerable portion of the core. The core surrounds...
Transformer With Winding Resistance
TRANSFORMER WITH WINDING RESISTANCE: In an actual transformer, the primary and secondary windings have some resistance represented by R1 and R2, respectively. These resistances...
Actual transformer and its phasor diagram at different load.
ACTUAL TRANSFORMER: In ideal transformer we have neglected the windings ohmic resistances and considered the pure inductive coils wound on a loss free core. But...
Ideal Transformer at Load and its Phasor diagram at different load.
IDEAL TRANSFORMER AT LOAD: When the primary winding of the transformer is connected across the supply mains and secondary winding is connected across the load...
Ideal Transformer at no load (Open Circuit Transformer)
When the primary winding of transformer is connected across of the supply mains and secondary is left open i.e no any load is connected across...
