Power Quality is any power problem manifested in voltage, current or frequency deviations that results in failure or miss-operation of customer equipment.
Power Quality is a set of electrical boundaries that allows a piece of equipment to function in its intended manner without significant loss of performance and life expectancy.
Misleading terms are frequently used to reference the problems of electrical power such as, bad power “dirty power” or “clean power.
General public may interpret these terms as describing the utility supply, instead of focusing on the quality of power at the point of utilization, Point of Common Coupling (PCC).
