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 with the loa…

Construction of DC Generator - Each Part Explanation

Electricity generated at all the power plants is alternating i.e., A.C. In order to generate direct current i.e., d.c. a commutator is used to convert the generated a.c. supply into d.c. supply. Hence, an electrical generat…

What is Blocked Rotor Test of Induction Motor ?

Blocked rotor test, it is quite opposite to 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 ci…

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 which has no iron and copper losses. It may, however, be noted t…
