4 Description

4.1 An overview of the main components of the Gemini 3 is shown Figure 1.

Figure 1 – Gemini 3 RTU Cabinet Layout

4.2 The Gemini 3 has remote control and monitoring facilities for up to four switches or circuit-breakers (or a mixture of both) using the DSM modules and is shown in Figure 1. Each switch/circuit breaker to be controlled and / or monitored needs an umbilical cable connection between the equipment and the Gemini 3.

4.3 Local control and monitoring is provided using the HMI.

4.4 The Gemini 3 is mains powered with a battery back-up and is self-monitoring.


Version: 1.0

Date: 27/04/2017


4.5 The Gemini 3 uses the DNP3 IP protocol to provide communication with PowerOn network management system for remote control and monitoring. Any appropriate IP compliant comms system can be used, such as:

O2 or Vodafone GPRS/3G networks via the dedicated UK Power Networks APNs.

Rented ADSL circuits.

UKPN SHDSL circuits.

UKPN Geostationary Satellite.

Fibre.

4.6 The Gemini 3 is also capable of utilising the Vodafone PAKNET system (EPN and SPN).

4.7 The IP comms networks will also provide remote configuration and monitoring capability from UKPN offices.

4.8 The Gemini 3 is capable of providing two internal fault passage indicators (FPI) on the FPM module, driven via the 3 phase RMU FPI CT inputs (where available). These are directly wired to RTU switch 1 and RTU switch 2.

4.9 Where RMU CT inputs cannot be provided to the RTU (old LPN spec RMUs for instance), or where additional FPIs are required, these can be facilitated using external FPI units connected to the RTU via the RMU marshalling box.

4.10 Connections to plant and equipment are made using the sockets provided on the bottom of the RTU, see Figure 3.

Figure 3 – Sockets on Underside of RTU

5 Comms Device Installation

5.1 Ensure the Comms Device mounting DIN rail is installed in the appropriate position for the Comms Device to be installed as shown in Figure 4. Note, the DIN rail may need to be repositioned depending on the Comms Device being fitted.

Figure 4 – Comms Device DIN Rail Installation


Version: 1.0

Date: 27/04/2017


5.2 Mount the Comms Device on the DIN rail as shown in Figure 5.

Figure 5 – Comms Device Installed

5.3 Connect the Comms Device power lead into the PSM DC outputs connector on terminals DC 1+ and DC 1-.

5.4 Connect the Comms Device power lead to the Comms Device.

5.5 If using GPRS/3G/4G Comms: Connect the ethernet patch lead to ETH0 of the MCM and to the comms device Ethernet port.

5.6 If using PAKNET Comms: Connect the comms lead to the port labelled either Comm 1 or RS232 A of the MCM and to the comms device serial port.

5.7 If a risk assessment of the location allows, the aerial should be mounted outdoors, however if not the aerial should be mounted as high as possible within the substation.

5.8 If the substation is underground, every effort should be made to place the aerial at street level, or as close as reasonably practicable.

5.9 If using GPRS/3G/4G Comms: The Aerial feeder should be passed through one of the stuffing glands already installed on the RTU. The aerial feeder cable may need to be packed out (with insulating tape or something suitable) to ensure the stuffing gland can be tightened to form a good seal around the feeder cable.

5.10 If using PAKNET Comms: The Aerial should be supplied with a stuffing gland already installed on the cable. Feed the cable and stuffing gland through one of the blanked 20mm holes on the bottom of the RTU.
