In this paper a review on power quality is discussed. Power quality is becoming a significant issue because of many reasons; few of these reasons are many instruments that are gaining familiarity in use to enhance the performance of energy system like advance power electronics and drivers of adjustable-speed motor. But the problem of using these instruments is that they enhance the level of harmonic components in distribution network.The control dependent devices and loads that relay on the microprocessor and microcontroller are most prone to problem of quality issue. Due to distortion in the system of energy there is severe effect on the interconnected networks that are common today. The reason behind it is the failure of an entire component. There is increasing growth of problems of voltages as voltage harmonics, over voltage, under voltage, etc. are causing awareness of issues in the power quality. So, the need of both better and high quality of power is increasing extremely among end users. Considering different cases any suitable option can be selected for power quality improvement.
