The new SEL-3530 Real-Time Automation Controller (RTAC) is a complete substation automation platform that incorporates state-of-the-art communications, security, and custom logic into exceedingly simple configuration software. The RTAC is the industry’s first automation gateway to include the IEEE C37.118 client protocol for receiving synchronized phasor messages. With the time-aligned information provided by synchrophasors, customers can simplify substation control and transmit information with highly accurate time stamps to SCADA for enhanced power system state calculations. Each RTAC includes:

• Complete IEC 61131 logic engine
• User security and logging
• Advanced data concentration
• Local and remote I /O
• Protocol conversion capabilities between multiple built-in client/server protocols.
