NES smart meters are critical devices within the NES System. They not only provide traditional electricity meter measurement functionality, but they also serve as advance power quality sensors for the distribution grid. NES smart meters meet the future market and regulatory needs of a utility by incorporating a rich set of features including prepay, multi-tariff abilities, remote firmware updates, remote connect and reconnect, tamper and outage detection, hardware extensibility, direct relay control, software-configurable service levels, and load factor monitoring. NES Smart Meters can be updated with new pricing, quality of service, energy management, and monitoring and control services even after they’ve been fully deployed.
