Description of contents: programme

Topic 1: REVIEWING BASIC CONCEPTS ON ELECTRICITY AND MAGNETISM. Maxwell equations. Core losses. Dielectric losses. Magnetic circuits. Self and mutual inductances. Topic 2: CONSTITUTION OF POWER TRANSFORMERS. Magnetic core, windings, insulation system. Transformer refrigeration. Basic concepts on maintenance. Topic 3: 1-PHASE TRANSFORMERS. No load performance. On-load performance. Overloads. Equivalent circuit. Efficiency. Voltage drop. Parallel operation. Short circuit currents. Inrush current. Topic 4: 3-PHASE TRANSFORMERS. Types of transformers. Phasor groups. No-load performance. Transformer performance under balanced and un-balanced loads. Zero-sequence impedance. Tertiary windings. Interconnected star windings. Three winding transformers. Autotransformers. Tap changers. Application of the different transformer types and phasor groups.

Learning activities and methodology

The learning methodology includes: - Lectures covering the main topics described within the course outline. - Case study and problem solving lectures, where some issues are addressed from a practical point of view. - Laboratory sessions

Assessment System

One writting exercise for each topic of the subject. With a score upper than 5.0 the exercise is passed. 
Those students with one or various failed exercised must perform a final exam of those failed exercises.

% end-of-term-examination 60
% of continuous assessment (assigments, laboratory, practicals...) 40
