Three-phase networks

Provide students with a scientific background to understand the concepts of balanced or unbalanced three-phase sinusoidal systems.

·       Determination of the connection of a three-phase load;

·       Determination of the voltage drop in a transmission line;

·       Determination of the current consumed by a three-phase installation;

·       Calculus of the power factor of a three-phase installation and power factor correction;

·       Study of harmonic pollution in an installation (filtering);

·       Calculus of the current in the neutral in the case of an unbalanced load;

·       Determination of the connection and the tap setting of a three-phase transformer;- Calculation of losses in a three-phase transformer.
