Remote Control Unit

The Remote Control unit is used to connect the Fusesaver pole mounted circuit breaker or CMR Compact Modular Recloser into a utility SCADA system. The Remote Control Unit is a pole mounted enclosure containing a microprocessor, a short range (approximately 20 m) radio used to communicate with the switchgear and a long range radio (or modem). The long range radio (or modem) is not supplied or fitted by Siemens unless specifically agreed to in the sale contract.

Successful application and operation of this equipment depends as much upon proper installation and maintenance by the user as it does upon the proper design and fabrication by Siemens.

Format and aim of the operating instructions

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:

Overview

The Remote Control Unit (RCU) is used to connect the Fusesaver (FSR) pole mounted circuit breaker or Compact Modular Recloser (CMR) into a utility’s SCADA system. The RCU is a pole-mounted enclosure containing a microprocessor, a short-range (approximately 20 m) radio used to communicate with the switchgear and a long-range radio (or modem). The long-range radio (or modem) is not supplied or fitted by Siemens unless specifically agreed to in the sale contract. The purpose of the RCU is to provide SCADA system access to monitor and control Siemens switchgear installed on distribution power lines. The RCU maintains an internal database which holds information on the switchgear being monitored and on the RCU itself. It is this data that is available over the SCADA system. The SCADA system accesses the RCU internal database with a SCADA protocol (such as DNP3) via a long-range radio or modem. Different SCADA protocols have different capabilities and methodologies. Typically, to update the firmware/configuration of the RCU and/or switchgear, the user needs to attend site to work directly with the equipment over the short-range (ANT) radio. Remote Engineering Access (REA) offers an alternative to travelling to site to make configuration changes and download events. REA allows a TCP/IP network connection from the Siemens PC Tools to the RCU, and through to the switchgear. REA enables the full functionality of the Siemens PC Tools as if the user is on site.
