Introduction
AMI system is the technology of automatically collecting data from energy metering devices and transferring that data to a central database by communication technology for remote control and analyzing
This AMI system is composed of management software, remote communication channel, power management terminal, the regional summary meter, the local communication channel, the user power meter and other equipments. Power companies can build AMI system to replace manual meter reading to save human resources, reduce meter reading costs and improve meter reading efficiency and success rate
Features
- DSLM / COSEM compatible
