Abstract-Considering the three main infrastructure of the actual power system (generation, transmission and distribution), where the latter receives least attention towards the modernizing grid. However, in the new context of smart grid, the distribution network plays an important role and topics related to monitoring of the power quality parameters are of great relevance to achieve the so called smart distribution network, providing valuable and reliable information to be used in control and protection schemes and also representing an important asset which aids distribution utilities and consumers to diagnose and fix the system's problems besides enabling regulators with tools for measuring the quality of services supplied by utilities. In this way, the proposed work aims at the development of a modular and smart device to be attached in public lighting systems, enabling the control and management of the lamp's parameters as well as to measure some power quality indicators from the distribution system and providing a communication infrastructure for the information exchange with a supervisory system.
