Smart Energy Monitoring, Metering & Control Session (DESIGN West 2012)

Government regulations and the cost of building power generating systems are two forces driving a more efficient power distribution system. To achieve the goal of enabling the smart grid, an integrated system for power measurement, monitoring, communication and control is essential. This session presents Microchip’s solutions from energy measurement devices through communications.
