Power quality audit of a school of engineering building - case study

Abstract

This paper presents a case study of power quality audit analysis for the School of Engineering building at The University of Jordan. The measurements of voltage, current, and power for seven days using Fluke power analyzer meter are presented in this study. Analysis of measured data shows that the system has two main problems. The first problem is current unbalance which causes a large residual current in the neutral. The second problem is the presence harmonic currents; especially the third harmonic current due to single-phase loading and fluorescent lighting system.
