Measurements and evaluation of harmonics in HV networks — Oman MIS case study

Abstract

This paper presents a case study about the impacts of industrial loads on power quality. A review of harmonics causes, negative impacts, mitigation techniques, quantification indices and limits are presented. Moreover, harmonics measurements at three grid station that supply the three main industrial areas located in the Main Interconnected System (MIS) of Oman are conducted. Measurement results are compared with limits specified by national and international standards.
