The open-circuit test is used to determine the impedance in the excitation branch of a real transformer. This test only measures the combined iron losses consisting of the hysteresis loss and the eddy current loss. The purpose of a short-circuit test is to determine the series branch parameters of the equivalent circuit of a real transformer. This test measures only the full load copper loss.

It is essential to know the relative polarity at any instant of primary and secondary terminals for making correct connections. When the two transformers are to be connected in parallel to share the load on the system. circuit Diagram Readings Equation Table Graph in detailed lab manual

1: To understand and measure different types of power 2: To know the importance of power factor and understand the procedure for its improvement Detailed Report of Lab Manual with equation and Circuit diagram.. Also observation and Conclusion is Mentioned

DC Compound Wound Generator: In Series wound Generators, the output voltage is directly proportional with load current. Series = Less Turn In Shunt wound Generators, the output voltage is inversely proportional with load current. Shunt = More Turn A combination of these two types of generators can overcome the disadvantages of both. This combination of winding is called Compound wound DC generator. Compound wound generators have both series field winding and shunt field winding. On...
