Power quality is the electrical network’s or the grid’s ability to supply a clean and stable power supply. As a result of the wide usage of electronic equipment, the development of electric power consumption and increasing nonlinear loads in power system leads to many power quality issues. If the power quality is poor, then it becomes the major issue due to increase in loss and heat, over burdening of the power system. All electrical equipment such as generator, motor, transformers, computers, house hold appliances fails when it exhibit power quality issues. This paper summarizes different power quality issues such as voltage variation, transient, harmonics etc.

power quality, voltage sag, voltage swell, harmonics distortions, frequency variation.
