Caracterização da Impedância de Acesso à Rede de Energia Elétrica Residencial para Uso em Sistemas Power Line Communications


This work aims to discuss the characterization of access impedance in Brazilian indoor electric power grids for designing Power Line Communication (PLC) system suitable for the Brazilian characteristics. With this regards, we briefly describe a measurement campaign that was carried out to measure access impedance considering the frequency band between 2 to 500 MHz. In the following, we present statistical analyses that address the behavior of such paramenter of typical electric power grids in Brazilian homes considering three important frequency bands for broadband PLC system applications. Finally, we show that the attained results provide very important information to design matching circuits that are useful to improve the performance of broadband PLC systems.
