Home smart grid device for energy saves and failure monitoring

home smart grid device for energy saves and failure monitoThe growing sensibility on energy consumption has focused people interest in energy optimization technologies. Non-intrusive load monitoring system (NILMS) are a cheap solution that require minimal equipment and installation time. The aim of the research is to develop a load analyzing platform for electrical devices to obtain information on their functionality and to display the costumer advantage to change their energy class. It monitors malfunctions or non-critical failures in realtime. It also counts the device operative life-time. The architecture is made of a local analysis electrical plug, which get the load information, and a central unit which elaborates data. The hardware implements a hall-effect ammeter, a power transformer and a micro controller (AT-mega328). The central unit is a small integrated computer (Raspberry). The communication between the devices utilize a low-range radio transmitter.ring
