27 Dec 2010 In this chapter, the power quality (PQ) report contains assessment of set of PQ parameters recorded indirectly at the AC generator (10,5 kV). Recorded values were compared with recommended values. Power quality report includes assessment of : • harmonic current factor (HCF) [4]. • system of currents

electronic and power electronic equipment has become more sensitive to voltage disturbances. • companies have become more sensitive to loss of production time. • reduced profit margins. • electricity is considered a basic right, which should always be present. • the interruption will lead to complaints, even if there are no
If the quality of the electricity your plant con- sumes is not what it should be, it's costing your company more than it should. Poor power qual- ity shortens the life of your equipment; trips your automated equipment; and produces extraneous heat that must be removed. Ironically, many of these issues originate inside the plant.
