Siemens Remote Control Unit™
Monitor and control your rural network

Answers for infrastructure and cities.
An intelligent solution
for rural networks
ƒƒImproving network
reliability in a cost
effective way is one of
the most challenging
tasks for power utilities
today.
2
ƒƒReducing the number
and duration of power
outages and limiting the
number of affected
customers are important
steps toward this goal.
ƒƒRemotely monitoring
and controlling the
network is key to
achieving this.
Siemens Fusesaver
Ever increasing regulatory demands means medium
voltage, rural electricity network operators are under
pressure to gather accurate data about network
performance.
The Siemens Fusesaver is a self-powered, electronically
controlled, single-phase fault interrupting device that is
installed in series with a fuse to protect that fuse from
transient faults. A short-range wireless communication
module is fitted to Fusesaver allowing you to:
ƒƒ manually operate using the Connect PC application
ƒƒ configure protection modes
ƒƒ download event log files from Fusesaver memory
ƒƒ view live data on status of each device including time,
type and magnitude of the most recent fault.
ƒƒ connect with Siemens Remote Control Unit
Control Fusesaver
Add the Siemens Remote Control Unit (RCU) and interface
Fusesaver with a SCADA system to provide remote access
to Fusesavers throughout your rural network.
Mounted beneath the Fusesaver, the RCU uses short-range
radio to communicate with Fusesaver, and long-range
backhaul radio or modem to remotely monitor and control
Fusesavers via the utility SCADA system to:
ƒƒ receive fault alerts
ƒƒ remotely operate Fusesaver sites
ƒƒ change protection modes from afar
ƒƒ saving line crew cost and effort, and improving
response time.

Bushfire
mitigation
Remote control of Fusesavers allows utilities in high-risk
bushfire areas or on high-risk days to change protection
by applying a different protection mode:
ƒƒ Normal protection
ƒƒ ‘Single shot’ using standard Fusesaver protection
ƒƒ ‘Single shot’ with instantaneous trip (half cycle) for
Code Red or extreme risk days
ƒƒ Protection off
Single shot modes allow supply to continue until any fault
occurs then the Fusesaver trips and stays open. Supply
can be reconnected remotely when required.
Local/remote lockout capability enables line crews to
disable Remote Control whilst they are working on the
downstream line, ensuring supply is not reinstated
unawares from afar.

Function
ƒƒ connects wirelessly to Fusesavers fitted with
Communications Modules via short range radio
ƒƒ simple installation, requiring only mounting and
connection of power and ground
ƒƒ powered from 115/230VAC low voltage supply or solar
panel (suitable locations only), eliminating the need for
an additional VT (option available)
ƒƒ power backup from 7AH 12V standard lead/acid battery
ƒƒ provides sheltered accommodation for the backhaul
radio/modem
ƒƒ DNP3 over serial link communications protocol suits
most SCADA systems / others available upon request
ƒƒ variety of settings, including protocol configuration and
radio interface. Configurable using the supplied PC
configuration/maintenance tool.
ƒƒ troubleshooting is simplified by an LED display showing
status of processor, power supply, communications and
Fusesavers. Additional fault finding can be performed
with the PC configuration/maintenance tool
ƒƒ purposely designed for outdoor use, not an adaptation
of a general purpose RTU
ƒƒ optional operator panel for local operator controls
ƒƒ use almost any radio/modem, with a user-settable DC
power supply, plus various signal interfaces, including
serial data and ethernet
