Premier 551 is a reliable, new-generation, three-phase transformer-operated smart electricity meter. It is equipped with a bi-directional communication unit to interact with the head-end system (HES) and plays a vital role in cost management. It supports 4G communication that ensures network redundancy by having GPRS as a fall-back option to suppress the black spots in the AMI network. It works as a common asset for import-export and forwarded mode. The firmware can be upgraded remotely without affecting the usual meter operations. It provides billing energies, history values, interval data and event alerts to the utility for billing cycle optimisation and effective network planning.
