Book is based on a professional course sponsored by IEEE and taught by the authors. Book is directed toward real problems and solutions, rather than a total theoretical treatment. Book can be used as the text for a course and as a reference. Dr. Kusko wrote The definition of power quality given in the Institute of Electrical and Electronic Engineers (IEEE) dictionary [37] is as follows: Power quality is the concept of powering and grounding sensitive equipment in a matter that is suitable to the operation of that equipment.
