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 or life expectancy. All electrical devices are prone to failure when exposed to one or more power quality problems. The electrical device might be an electric motor, a transformer, a generator, a computer, a printer, communication equipment, or a household appliance. All of these devices and others react adversely to power quality issues depending on the severity of problems. This paper reviewed the power quality problems, effect of power quality problem in different apparatuses and methods for its correction. Some power quality enhancement devices are also listed. It is necessary for engineers, technicians, and system operators to become familiar with power quality issues.
