It is not enough to have power supply. The characteristics of supply voltage at all-time are very essential for smooth operation and service-life of equipment. The voltage characteristics determine the quality of the power supply. The degree to which the supply voltage characteristics conform to the acceptable standard is referred to as Power Quality. With ever increasing use of power electronic devices in domestic and commercial settings as well as sensitive equipment in the industries for automated production, the need for maintaining good power quality has become necessary. This paper elucidates on Power Quality as well as issues associated with it. The causes and consequences of power quality problems are discussed. Techniques for mitigating power quality problems are presented.
