Hunting in Synchronous Motor - Causes & Prevention

What is Hunting (or) Surging (or) Phase Swinging ?      When a synchronous motor is loaded, there exists a phase angle between rotor and field ' α '. When load increases slowly, angle ' α ' also increases so t…

Three-Phase Transformer Winding Connections

In a single-phase as well as three-phase transformer the windings are placed on the core structure which is made up of laminated steel core. This core structure which supports the two windings of the transformer is placed i…

Transformer with Leakage Reactance & Leakage Flux

What is Leakage Flux in a Transformer ?      We know that all the flux linked with primary winding is also linked with the secondary winding. But, in the actual transformer the total flux created does not link with the primary…

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…
