UNIT I: 3-PHASE CIRCUITS, POWER MEASUREMENTS AND REACTIVE POWER COMPENSATION.
This Unit will allow the student to understand how to analyse 3-phasecircuits under much balanced or unbalanced conditions
Initially the unit covers the basic concepts for the analysis of balanced circuits. It continues covering unbalanced circuits, the different methods to measure the electrical powers and the compensation of reactive power.
• Introduction: Generators, loads and 3-phase circuits
• Balanced 3-phase circuits. Voltages and currents.
• Conversion of 3-phase sources and loads.
• Analysis of balanced 3-phase circuits.
• Powers in balanced 3-phase circuits. Compensation.
• Analysis of unbalanced 3-phase circuits.
UNIT II: TRANSFORMERS
This Unit will allow the student to learn about the constructive characteristics of the transformers, to determine his characteristic parameters and to understand the machine main properties and his utilization in the electric systems.
• Analogies between electric and magnetic circuits.
• Introduction to the transformers: constructive aspects.
• The ideal transformer.
• Operation of the real transformer.
• Equivalent circuit of the single-phase transformer real: e.m.f's and voltages.
• No-load and in short-circuit tests of the transformer.
• Voltage drops , losses and performance of a transformer.
• Autotransformers.
• 3-phasetransformers: Constitution, conection diagrams and tests.
• Instrument transformers.
