Complete Harmonic Directionality Analysis in Power Electrical Systems with Power Quality Analyzer Meters Using SWAP SMART©

This paper presents 5 different methods to analyze the harmonic directionality (identify the harmonic source) in power systems and any kind of power electric circuit (industry, houses, buildings, power systems, etc). In order to do this, the measure of power quality analyzer (class A according IEC 1000-4-30) were used in the point of common coupling (PCC)with out disconect the load. The paper describes the methods used and insert a new novel method that allows to determine the percentage of contribution of the load and the grid (electrical network). All the analysis is done using SWAP Smart© (Software for Analysis of Perturbation in Power Quality), which a unique software worldwide.
