Generators and Transformers

The losses in the core, windings and additional losses in generators and transformers. Type of  windings (Y, D, Z). Magnetization problems of generators and transformers. Dynamic analysis of short circuits in generators and transformers. 

Inrush phenomenon of generators and transformers. Various types of cooling (ONAN, ONAF, OFAF …). Attenuation of short circuits. 

Basic tests of generators and transformers.  
Operating conditions (isolated operation, operating on a rigid network, synchronous compensator). Oscillations in generators. Synchronous reactance. Transient reactance. Sub-transient reactance. “Per-unit” system. Generators and transformers presented by symmetrical components. Shift transformers. 

Acquiring in-depth knowledge of different types of generators and transformers, their properties, design features and applicability.

Lectures, demonstrations, work with computer tools, laboratory work, coursework, project work.
