The Institute of Electrical and Electronics Engineers' (IEEE) Standard 1100-2005 has defined power quality as a concept of powering and grounding sensitive electronic equipment in a manner that is suitable for the operation of that equipment (Institute of Electrical and Electronics Engineers [IEEE], 2005). Power quality can also be used to describe different electromagnetic phenomena that characterize the voltage and/or current at a given time and at a given location on a power system (IEEE, 2009). Electricity providers have always faced the task of ensuring compatibility between their power source and the load it serves. Concerns about power quality have increased as electronic loads and information technology equipment proliferate on power systems (IEEE, 2009). This thesis will discuss fundamentals of power quality and power quality standards. The document also includes information about common power anomalies and mitigation techniques.
