There are two most common methods to calculate the transformer voltage drop-Approximate Method and; Exact Method. The Approximate Method of Transformer Voltage drop calculation in detail is
Transformer Total Voltage Drop
Total Approximate Voltage Drop of a Transformer During the no-load condition, induced voltages at the primary and secondary windings are equal to the applied voltage and secondary terminal voltage respectively. If 0V2 is the secondary terminal voltage at no load, we can write E2 = 0V2. When the transformer is on no-load, then V1 is approximately equal to E1. Hence E2 = KE1 = KV1. Also,E2 = 0V2
Simplified Diagram of Transformer

The combined vector diagrams are shown herewith in the figure VD-A, VD-B, and VD-C. The vector diagram of Fig. VD-A may be considerably simplified if the no-load current I0 is neglected. Since I0 is 1 to 3 percent of full-load primary current I1,

Magnetic Leakage of a Transformer Breaks Ideal Characteristic
Fig-1: Magnetic Leakage of Transformer How does magnetic flux determine the ideal transformer is not possible in practice? Generally, it is assumed as our elementary knowledge about the transformer theory that the flux linked with the primary winding is also linked to the secondary winding. But in a practical transformer cannot link all the fluxes to the secondary windings that is linked at
Transformer Equivalent Resistance
Fig-1: Transformer Equivalent ResistanceFig-2: Transformer Equivalent ReactanceHow to Calculate the Transformer Equivalent Resistance and Reactance? The transformer’s impedance is given in percentage or per unit system. It is because of this reason that the impedance value for the transformer is represented as two values one wrt to low voltage winding and the other is high voltage winding. Both
Transformer with Losses but no Magnetic Leakage
To base our knowledge about the electrical transformer, we assumed an ideal transformer i.e. one in which there were no core losses and copper losses. But in practical conditions of a real transformer, it requires that certain modifications be made in the foregoing theory. When an actual transformer is put on the load, there is an iron loss in the transformer core and copper loss in the
Transformer on Load
When an electrical load is connected to the secondary winding of a transformer and the transformer loading is, therefore, greater than zero, a current flows in the secondary winding and out to the load. This secondary current is due to the induced secondary voltage, set up by the magnetic flux created in the core from the primary current. Transformer On-loadThe great electrical book writer B.L.
Transformer on No-load
The answer to the question lies in one of the assumptions made for an ideal transformer. The core of an ideal transformer is supposed to have infinite permeability. So, no MMF is needed to produce working flux. But, in a practical transformer, the permeability is not infinite so we need a certain current for a certain amount of MMF which will produce the required working flux.No load current has
