Power quality improvement factors : an overview

The power quality has started to play an important role in the electronic industry. As the power providers are turning to smart grid and smart meters, the standards for power quality needs to be revisited. The power quality can be categorized into two groups, one addressing the standard for the power quality supplied at the grid level and the other group which deals with the factors that affect the power quality at user level. These factors include harmonics, voltage changes, sags, transients, voltage unbalance, etc. These factors will provide us in-depth details on the power system. In this paper, an overview of various factors will be presented in order which can affect the power quality of the system. The paper will also look briefly at the measurement techniques used to measure them
