Q&A
Q: What are the advantages of the AMI system?
A: 1. Flexibility of configuration:
1.1 Function modularization: It can customize the equipment and separately deploy the modules according to the size of the management scale.
1.2 The function is hierarchically designed, which can guarantee clear logic, convenient maintenance and the stable operation.
2. Diversity of management:
Managing range covers the different types of energy consumed objects, such as Substations, Users with special transformer, Distribution transformers, Residential Users, etc. It can configure the relevant managing function according to the type of object.
3. Compatibility of equipments:
The users can choose the appropriate mode of network (such as GPRS, PLC, WSN or 485), the collection equipments (such as various energy meters or concentrators) and the operation protocol of equipments according to their own situation. The system can provide support or expansion.
