RTAC and Axion Advancements for RTU and Substation Gateway Applications

Date held: Wednesday, March 22, 2023
Duration: 1 hour

Remote terminal units (RTUs) and substation gateways perform a critical role in power systems—concentrating data at substations, converting protocols, and communicating with central SCADA systems. The SEL Real-Time Automation Controller (RTAC) and SEL-2240 Axion offer simple, economical replacements for legacy RTUs.

In this recorded webinar, Engineering Manager Darrin Kite discusses SEL solutions for substation gateway applications and RTU replacements, including the new SEL-3350 3U RTAC model. He will also talk about recent advancements that simplify configuration and improve RTAC data collection and monitoring.

Topics include:

  • An overview and comparison of the hardware options available, including the new SEL-3350 3U model—which represents the next generation of the popular SEL-3530 RTAC and offers five times faster processing power.
  • The range of supported protocols, including the newly added OPC UA Client/Server and recent enhancements for IEC 61850 protocols.
  • The Simple Tag Mapper tool that provides enhanced workflows for mapping data points.
  • Additional capabilities for engineering access, data collection, compliance support, and substation monitoring.
  • Troubleshooting tools available, including the new online protocol dissector.
  • Integration with Blueframe applications, including:
    • The Data Management and Automation (DMA) suite for centralized data collection.
    • The new RTAC Dashboard application for monitoring the status of RTUs deployed throughout the system.
