1. Grid Metering Processes
Commercial process
Billing System
Energy values (kWh, kvarh)
Grid Meter
Network Management System
Network values (U, I, P, Q)
Operational process

2. Grid Metering Measurement
Measurement quality exceeds Class 0.2S requirements.
Measurement system 5 times faster as for industrial meters.
Intergrated billing power quality for voltage dips and interruptions.
Easy adaption for primary values.
Scalable meter functionality.

3. Grid Metering Communication
Modular communication separated from measurement.
Standard protocol DLMS (IEC ).
Open for other standard protocols for network management.
Data traceability
DLMS = Device Language Message Specification

4. Grid Metering Standards
