In today`s world of Smart Grid, deregulated electric power systems, and high use of novel power electronics, power quality is an important commodity. This course is aimed at familiarizing the concepts of voltage sags, harmonics, momentary disruptions, and waveform distortions. A theoretical and mathematical basis for various indices, standards, models, and analyses techniques will be presented. Additionally, sources of power quality problems and some remedies for improvement will be discussed. This course covers a wide range of topics, including: Sags; swells; under or overvoltage; harmonics; transients; flicker; electrical noise; interruptions wiring and grounding issues; Instruments and Analyzers; Power Characteristics; standards & codes.
o Recognize symptoms of power quality problems including sags, swells, flicker; under or overvoltage, harmonics, transients, electrical noise, interruptions wiring and grounding issues.
o Classify power quality events according to IEEE and public utility standards.
o Explain proper application and interpret results of power quality monitoring equipment.
o Recommend viable solutions including UPS, line voltage regulators, transient (surge) suppressors, harmonic filters, line filters, power conditioners, isolations and zig-zag transformers, proper wiring and grounding etc.
