Systems & Electronics
Remote Terminal Unit for remote control and surveillance of secondary substation in medium voltage networks.
The UP devices, installed in secondary substations of medium voltage distribution networks, are intended to:
Monitor the operation of the medium voltage networks (detect switchgear status and fault signals, acquire field measurement);
Remotely control the secondary substations switchgears;
Implement automatic procedures for the selection of the faulty branch.
The WM-UP8(16) is composed of:
Elaboration Unit (UE) device, standard version (UE8) or extended (UE16)
Power supply and battery charger (PSBC) device
Cabinet and wiring
UE Elaboration unit
The UE device is the hearth of the UP since it hosts the monitoring and remote-control logic of the secondary substation.
UE can record the substation temperature using a 2 or 4-wires temperature sensor.
The UE is suitable for mounting on 19’’ standard rack and can be provided is two versions:
UE8 or Standard version, 4U high
UE16 or Extended version, 7U high
IEC 60870-5-101 via RS232 port
IEC 60870-5-104 via Ethernet or RS232 port
MODBUS TCP/IP via Ethernet port
IEC 61850 MMS
The PSBC charges the batteries that supply power to the components installed in the secondary substation (UE, RGDAT/RGDM, switchgears) and supply +12Vdc to the DCE.
The PSBC is suitable for mounting on 19’’ standard rack and is 3U high.
Protocols are also available in their secured version according to IEC 62351
