4DCT / 4GWC data concentrators and AMI gateways for substations
Country: Spain · Model: 4DCT / 4GWC
The 4DCT / 4GWC data concentrators and AMI gateways are installed in transformer substations to collect readings from PLC meters over PRIME 1.3/1.4 or Meters & More and pass them to the metering centre under DLMS. The same device manages the PLC network of its substation and monitors the LV network.

Description
In a PRIME network the concentrator plays the role of the base node, that is, it registers meters, builds routes through intermediate nodes and monitors the state of the channel. Support for Meters & More alongside PRIME 1.3/1.4 makes it possible to serve a mixed fleet, when meters of different PLC standards stand in one district. The device accumulates the collected data locally and passes it to the upper level under DLMS. The LV monitoring function shows the operator the state of the low-voltage network behind the transformer. The channel to the metering centre is encrypted with TLS, and files are transferred over SFTP. The communications department tracks the state of the device itself over SNMP in the same monitoring system as routers and switches.
How to choose
The deciding parameter is the PLC protocol of the meters that are already installed or will be installed in the substation zone. For a fleet on PRIME 1.3/1.4 the pairing with 5CTB meters works within one standard, and Meters & More is needed where devices of another PLC standard remain. 5CTA meters with LTE do not need a concentrator, because they reach the server directly. If the operator needs an energy balance for each outgoing feeder, the 4SLV / 5LVS system with LPCT sensors and 5CTI units is added to the concentrator.

FAQ
Which PLC protocols does the 4DCT / 4GWC concentrator support?
PRIME versions 1.3 and 1.4 and Meters & More. The device exchanges data with the upper level of the metering system under DLMS.
Is a concentrator needed for meters with an LTE modem?
No, the 5CTA meter sends data over the mobile network without intermediaries. The 4DCT / 4GWC is needed for PLC meters, for example the 5CTB with PRIME 1.3/1.4.
How is data transfer from the AMI concentrator to the metering centre protected?
Communication with the metering centre runs over a TLS connection, and file upload over SFTP. For the communications department the device is accessible over SNMP.
Where is the AMI data concentrator installed?
In the transformer substation next to the 0.4 kV LV board that supplies the meters. From there the device has PLC communication with the outgoing lines and monitors the LV network.
What should be added to the 4DCT to monitor each 0.4 kV feeder?
The 4SLV / 5LVS system with LPCT current sensors and 5CTI measuring units. It calculates the energy balance and links meters to feeders, while the concentrator collects the readings themselves.
