SUBJECT I: CIRCUITS OF THAT TRIPHASES. MEASURES. COMPENSATION.
With this subject, intends that the student know to #analyze circuits triphases so much balanced how unbalanced. It initiates the subject with the basic concepts stop the analysis of circuits balanced. It continues with the unbalanced circuits, the different methods to measure the power and the compensation of power reactivates as well as the methods to determine the sequence of phases. It finalizes with an introduction to the symmetrical components. |
• Introduction: Generators, cargos and circuits triphases.

• Conversion of sources and triphases charges.
• Analysis of circuits triphases balanced.
• Power in circuits triphases balanced. Compensation.
• Analysis of circuits triphases unbalanced.
• Determination of the sequence of phases and measure of power and energy.
• Symmetrical components. |
SUBJECT II: TRANSFORMERS
With this subject, intends that the student know the constructive characteristics more important of the transformers as well as determine his characteristic parameters and main properties, as well as his utilization in the electric systems. |
• Analogies between electric and magnetic circuits.
