Course detail

The power quality and EMC 2

FEKT-LPQ2Acad. year: 2011/2012

The power quality is characterized by the steady-state nominal frequency sine wave of voltage, which is symmetrical in the three-phase supply network. The power quality depends on a quality of the electrical power generation, the quality of the transmission and the distribution and on the quality of electrical power consumption as well. Backward disturbing influences of the individual power system components and their compatibility and cooperation in an industrial and distribution supply networks are the content of this course. The mechanisms of the power system compatibility assurances are demonstrated at practical examples.
