Nov 07, 2011 · Transformer being highly inductive device works on lagging power factor unless the load of highly capacitive nature is connected across the secondary winding to make overall circuit resistive purely or capacitive in nature. CIRCUIT DIAGRAM: Figure (1): Circuit Diagram for 1-Phase Transformer. PROCEDURE: Make the connections as per the circuit ...

In addition, the transformer windings may be considered to have polarity marks on each winding to signify all terminals that have the same polarity at any given time. For example, when H1 is positive with respect to H2 in the diagram above, X1 will also be positive with respect to X2 and T1 will be positive with respect to T2 and also to T3.

Develop the equivalent circuit of single phase transformer from the first principle. Draw the phasor diagram of a transformer under full load condition at lagging power factor and explain. The O.C and S.C tests on a 5kVA,230/110V,50Hz transformer gave the following data: O.C test (h.v side):230V, 0.6A, 80W. S.C test (l.v side):6V, 15A, 20W
