For successful secondary substation automation it is vital to have technically proven components with standardized interfaces, and a straightforward implementation process. Viola RCC meets all these needs. It is an integrated solution for secondary substation automation, including secure wireless communication for SCADA connectivity.
Viola RCC uses field-proven components with tested interoperability, thus dramatically reducing project-specific engineering work. Cloud-based tools can be used in configuring and commissioning the system, hence it is ideal for secondary substation automation.
Viola RCC provides features such as remote
RMU management with secure, always-on wireless connectivity for SCADA with IEC-104 protocol support, power quality metering, directional fault indication in medium voltage lines, plus intelligent battery monitoring.
Wireless connectivity is implemented via commercial mobile networks, thus reducing investment and operating costs.
Viola RCC – a complete package for secondary substation automation, including all necessary RTU
(Remote Terminal Unit) and remote control components
Reliable two-way communication is based on commercial wireless GPRS/EDGE/3G/LTE networks, using standard SIM cards
Viola Systems delivers a complete, secure end-to-end connectivity solution that seamlessly integrates remote devices and sites with centralized management systems such as SCADA. No changes to existing systems are needed. The Viola
M2M solution is an install-andforget-it, hassle-free approach. In addition, the Viola M2M Solution is operator-independent, allowing customers to implement two-way data communications in a similar manner all over the world.

reliable and secure Communication
Arctic Control provides always-on two-way communication based on commercial wireless EDGE/GPRS networks.
Standard SIM cards can be used, leading to low operating costs for the complete solution. Arctic Control utilizes
VPN and a static IP-based communication channel for reliable and secure end-to-end communication.
Battery secured operation – built-in battery charger with advanced battery control
Temperature compensated charging, battery condition monitoring and testing. Battery voltage is constantly measured under network fault conditions. Advanced battery controls optimize the lifetime and maintenance intervals of back-up batteries in the control assembly.
Inputs and outputs / physical interfaces
Arctic Control is equipped with numerous input and output connections to manage control operations communicated to SCADA via the wireless network.
The IEC-104 protocol is used as a communication protocol between SCADA and Arctic Control.
Connections for other devices
Arctic Control has two application serial ports and one
Ethernet port. In addition, conventional IEC 60870-5-
101 devices can be attached to a modern TCP/IP-based
IEC 60870-5-104 control system, due to the protocol conversion capability of Arctic Control. The RJ-45 connector is for a 10/100 Mbps Ethernet connection, and it can be used for various LAN applications.
Front panel leDs
The complete operational status of the device is indicated by a group of LEDs.
Disconnector motor overcurrent detection and shut-down
Arctic Control has software fuse functionality – it protects the motor by shutting off power to it before the motor’s own fuse blows. The software fuse reduces maintenance calls to replace the physical fuse. It also avoids unnecessary breakdowns of the motor, resulting in large savings in both time and costs, in addition to the increase in operational efficiency.
Disconnector control and monitoring
Arctic Control provides remote monitoring and control of multiple switchgears and disconnectors.
1–3 disconnectors can be connected to one unit. LEDs show the disconnector position and earthing status.
Arctic Control supports both local and remote use.
Heater control
Arctic control can control a heater to limit the effects of ambient temperature variations, such as condensation in the cabinet in which the devices are located.
Configuration
The devices can be configured using a graphical user interface via an internet browser or via a conventional console interface. Configuration settings and adjustments to the devices can be implemented remotely by uploads over the network from the central control center.
