Narrowband powerline communication systems are widely used in many applications, such as smart metering devices, home automation and low-speed command and control systems. However, power lines were not designed for data transmission and they represent a harsh environment for communication. In the specific bibliography, it is possible to find studies that show the diverse issues of Narrowband Powerline Communication, being the impedance of the grid one of them. The main objective of the present work is to provide a study on the impedance of the grid over this communication band. This study was done in a University environment which has a diverse number of unknown loads, considering the variation with time and location. The data acquisition system developed to conduct the study is shown. The analysis of the results shows that the local grid exhibits issues as least as severe as the ones presented by other authors in different countries and environments.Downloads
