Analysis of Power Quality in Hostel and Academic Buildings of Educational Institute

Abstract

In last decades, electronics and telecommunications have known unexpected development; the number of nonlinear loads has increased, along with this the disturbances in power quality also raised. Poor quality in power causes more losses and will cause malfunction, leading to replacement of particular connected load. This paper presents the preliminary results of Power quality survey done in academic and hostel buildings of VIT University. The power quality survey is necessary to record all events over an enough long time interval. Here we collected various parameter readings from all electrical feeders of for different buildings. This paper analyzes the complexities as well as consequences of power quality disruptions. In order to reduce the huge amount of data by recording and analyzing several electrical parameters over certain duration of time, some recording limits as per IEC standards are to be set. For particular feeders where limits exceed the set values, various strategies to enhance the quality of power and minimize the losses are implemented.
