Current and voltage harmonic levels in LV grids depend not only on the harmonic emission of non-linear loads, but also on the characteristics of the grid and the voltage distortion of the upstream grid. Based on several measurements, it was found that Colombia and Germany have considerable differences in the current harmonic emission of electronic devices and voltage distortion in the LV-grids. These differences are the result of different regulation methodologies and the characteristics of the grid. Detail measurement campaigns are needed in both countries in order to verify the voltage and current harmonic levels, and to analyze the network efficiency and hosting capacity in terms of harmonics.

Los niveles de distorsión armónica en las redes de baja tensión no dependen únicamente de las cargas no lineales conectadas al sistema, sino también de las características de la red y la distorsión de tensión proveniente de la red de media tensión. Considerables diferencias en la emisión de armónicos de equipos electrónicos y los niveles de distorsión de tensión en las redes de baja tensión en Colombia y Alemania fueron identificados a partir de varias mediciones. Estas diferencias se deben principalmente a la normatividad y las características de las redes en cada país. Se recomienda realizar  campañas de medición en ambos países para verificar los niveles de distorsión y analizar la eficiencia y la capacidad de la red en términos de armónicos.
