Back-to-Back Test or Sumpner's Test on Transformer

Why Sumpner's Test or Back to Back Test? For a transformer, the temperature rise is an important factor to be noted before making it into operation. The temperature of a transformer changes in proportion to the load. Because…

Construction of DC Generator - Each Part Explanation

Electricity generated at all the power plants is alternating i.e., ac, in order to generate direct current i.e., dc, a commutator is used to convert the generated ac supply into dc supply. Hence, an electrical generator with a co…

What is Blocked Rotor Test of Induction Motor ?

The blocked rotor test, it is quite opposite of the no-load test of the induction motor. Usually in transformer tests, if we want to find the behavior of a transformer on loading and on no-load, it can be done by using open circu…

What is Ideal Transformer ? - Phasor Diagram & Model

What is Ideal Transformer? An ideal transformer is one that has no losses i.e., its windings have no resistance, there is no magnetic leakage, and hence it has no iron and copper losses. It may, however, be noted that it is impo…
