Substation Automation
Enable high-performance control and monitoring schemes. Protection applications include directional element-based bus protection and replacement of tone-channel equipment for communications-assisted blocking, unblocking, permissive, and transfer trip schemes.
Automation Controllers
SEL Real-Time Automation Controllers (RTACs) provide automation and data management in the substation. They manage and archive system data, allow viewing of real-time information, and control substation equipment. Additionally, SEL RTACs allow you to integrate an HMI for control, annunciation, and alarm management.
