3.11 can now be represented as a semi-ideal transformer having lumped resistances R1 and R2 and leakage reactances symbolized as Xl1 and Xl2 in series with 

The Equivalent Circuit of a Practical Transformer Practical Transformer and Equivalent Circuits Transformer windings are made mainly of copper. Although copper is a very good conductor, it still has some internal resistance.

The induced emf E 1 is equal to the primary applied voltage V 1 less primary voltage drop. This voltage causes current I 0 no-load current in the primary winding of the transformer. The value of no-load current is very small, and thus, it is neglected. Equivalent Circuit of Transformer, Basic Electrical Engineering, Btech first year Equivalent Circuit of Transformer The concept of Equivalent Circuits exists to help us analyze transformer as by using this concept, we can transform all the parameters to either side. (b) Equivalent circuit referred to primary I1 I2 V1 a Z (c) Equivalent circuit referred to secondary I'1 V1 Z2 S Ideal Transformer Rc1 Im I1 Xm I I0 c1 Rc1 Xm X' m R'c1 Figure 24.5: Equivalent circuit showing core loss and magnetizing current. 11 2 1 2 ' This transformer is operated in the step-down mode and delivers 75% of its rated power to a load that has a power factor of 0.93 lagging.

And build up an equivalent circuit model that can be solved to find things like the efficiency. I would also note that if you found the derivation of the output voltage by manipulating the ideal transformer circuit to be unfamiliar, or you need a brush-up on how to do that.

#Transformer #Equivalent #Thevenin This was a question asked by a viewer. We have been given an ideal transformer with N₁ no. of primary turns and N₂ no. of The Equivalent Circuit of a Practical Transformer Practical Transformer and Equivalent Circuits Transformer windings are made mainly of copper. Although copper is a very good conductor, it still has some internal resistance. Transformer Equivalent Circuits All non-ideal transformers have: - Winding resistance - A core with finite permeability - Leakage flux - Hysteresis - Eddy current losses Mutual flux that links both coils Primary leakage flux Current flows in Current flows out Can be represented as a resistor and inductor in series with transformer 17 Equivalent circuit of transformer Resistances and reactances of transformer, which are described above, can be imagined separately from the windings (as shown in the figure below). Hence, the function of windings, thereafter, will only be the transforming the voltage.

• The effect of leakage flux can be included by adding two inductances, L p and L s, respectively, in the primary and secondary winding circuits. The combination of the leakage reactances is called the equivalent reactance.

THE IDEAL TRANSFORMER Because we are dealing with balanced 3-phase motors we can achieve considerable simpliWcation by developing single-phase models, it being understood that any calculations using the equivalent circuit (e.g. torque or power) will yield ‘per phase’ values which will be multiplied by three to give the total torque or power. #Transformer #Equivalent #Thevenin This was a question asked by a viewer.
