Harmonics assessment and analysis at low voltage networks — Case study: Mutah University campus (Engineering building)

Driven by continuous increase and high penetrations of non-linear loads, power electronics based loads at Low voltage (LV) and Medium voltage (MV) electrical networks, power quality become an important issue not only for customers but also for the utilities. Mutah University is a rich place of these loads such as: personal computers, printers, fluorescent lamps and other sources might cause harmonics problem, therefore, it is imperative to examine and quantify power quality profiles and harmonics pollution in the campus. In this paper, a case-study analysis for harmonics profile in electrical distribution system of Mutah University is presented. The study focuses on one of the campus buildings (Engineering Faculty Building). Extensive field measurements and analysis are conducted; the harmonics profile at the main distribution board (MBD) and for single-phase loads are examined.
