Data concentrator units for PLC smart meters
Data concentrator units used to interrogate meters, to process and store the information it receives, and to send this data to a centralised Information System.
Installed on the LV side of the MV/LV distribution substations, the hub is a powerful computerised unit, which primarily:
- Centralises and processes meter data from a cluster of electric meters communicating via PLC (Power Line Communication)
- Sends data collected to an IS (Information System) via GPRS
- Sends remote handling requests from the IS to meters
- Tracks LV distribution network voltages
- Provides the interface with other devices (e.g. Fault Detectors)
CAHORS DCU are part of Enedis Linky® smart metering program.
