Maintain a perfect sine wave voltage and constant magnitude is really challenging, due to different aspects like the load unbalance, distribution line impedance, poor power factor, non-linear loads etc. Increase in the usage of the semiconductor devices in the appliances that are used in the consumer level as well as industrial level is distorting the voltage quality. Some of the major voltage quality issues that are faced by the utility as well as the consumer are discussed. Those voltage quality issues have deleterious effect on the customer appliances, and make them prone to failures. These failures monetarily affect the consumers that have sensitive equipment. Different mitigated solutions are proposed to improve the voltage value fluctuations. The paper mainly covers the different reasons of the voltage value distortions that are caused by the different aspects, starting from the distribution network constraints to the faults that are very common in the low voltage system. The voltage quality problems that are severe from customer point of view are:

-voltage magnitude variation

-voltage sags

-voltage harmonics
