Engineering Access and SCADA—Deploy the RTAC as a data concentrator using protocols such as IEC 61850 MMS client, Modbus, DNP3, IEC 61850 GOOSE, LG 8979, IEC 60870-5-101/104, or Mirrored Bits communications, and integrate both serial and Ethernet intelligent electronic devices (IEDs). Enable logging on any system or IED tag to view and archive station-wide event records. Enable multiple SCADA connections via serial or Ethernet communications.
Distribution Automation—Improve the reliability and reduce the cost of a distribution system by commissioning the RTAC as a Distribution Automation Controller (DAC). A DAC provides wide area Automatic Network Reconfiguration to minimize outage size and area by isolating faults and restoring power to un-faulted areas. It also provides Dynamic Feeder Optimization functionality, which allows distribution tap changers, voltage regulators, and capacitor banks to work together as a team to control power factor and reduce voltage.
Substation Human-Machine Interface (HMI)—Provide cost-effective local and remote monitoring, control, and annunciation for substations and other processes by installing the optional web-based HMI, available for the RTAC and SEL-2240 Axion. acSELerator Diagram Builder SEL-5035 Software easily maps the RTAC tag database to reduce screen development time.
Secure Communications and User Management—Employ the RTAC, SEL-3620 Ethernet Security Gateway, and SEL accessories to secure your automation network. Per-user security profiles provide compliance with role-based requirements. The system supports intrusion detection, notification, and logging to help maintain perimeter integrity. Secure Shell (SSH) and password management provide encrypted engineering access through the RTAC.
Time Synchronization—Implement time-code inputs, such as IRIG-B and Network Time Protocol (NTP), to distribute precise time to connected IEDs. In the absence of an external time source, use the internal information processor clock to generate IRIG-B for connected devices.
Avoid security concerns and obsolescence risks associated with Microsoft Windows operating systems because the SEL RTAC uses the secure and proven SEL real-time Linux operating system.
Higher Processing Power
Take advantage of the rugged computing systems platform and the powerful logic engine of the SEL RTAC for high-speed automation synchrophasor processing and distribution automation on the SEL RTAC.
Renowned SEL Reliability and Support
The rugged computers are designed and tested to meet or exceed IEEE 1613 and protective relay specifications for harsh environments and to withstand vibration, electrical surges, fast transients, and extreme temperatures. The SEL RTAC running on an SEL rugged computer operates reliably, even in the most challenging environments.
Optional Integrated Web HMI
Create web-based HMI one-lines, annunciator screens, and control scheme visualizations with the optional acSELerator Diagram Builder SEL-5035 Software. Directly connect your monitor to the integrated video port.
Concentrate and manage data from new and legacy relays and other intelligent electronic devices (IEDs) using the extensive supported protocols:
