Resumo

This paper presents an analysis of the harmonic distortions caused by residential loads on a distribution transformer. The study was performed in two stages, the first one being through measurements carried out in three households with different consumption patterns (high, medium and low) in order to identify the main nonlinear loads and to verify the behavior of the harmonic distortions in a residential environment. The second stage presents a model of a low voltage distribution network, through which different scenarios are simulated using the load data collected in the measurements of the three residences. Through this study it is possible to evaluate the harmonic distortions in a distribution transformer caused by residential loads.
