Power quality issues are becoming more significant day by day because of increase in the usage of modern equipment's which is having power electronic circuits for better control and energy saving. These devices are responsible for generating more harmonics in the power system. Both end users and utilities are highly concerned of power quality as it is devastating the power system as well as the devices connected to it. Industries and commercial nonlinear loads which are connected to power system are the major reasons for majority of power quality issues. Power quality (PQ) survey will help in understanding the behavior of power system with a goal to develop standards of power quality. The Survey will provide the present trends of power, voltage, current and other electrical parameters which will be helpful to upgrade the limits. PQ survey will also guide the electrical and electronic equipment designer to extrapolate the electrical parameter as per present trends and design the future products which can with stand adverse situations. In this report the results of power quality survey conducted in VIT University with respect to different load feeders are presented with PQ issues and suggestions given to improve the power quality.
