SEL Events at the Georgia Tech Protective Relaying Conference


SEL is excited to participate in Georgia Tech’s 71st Annual Protective Relaying Conference. We will host a number of activities associated with the conference, including a complimentary, full-day technical seminar. SEL engineers will present nine technical papers at the conference on topics such as implementing a microgrid, high-speed reclosing, advanced generator protection, and cybersecurity. In addition, we will participate in the vendor exhibition, where we will showcase many new technologies and have engineers on hand to help you with your power system challenges. We look forward to having you join us!

Technical Seminar

Georgia Tech Hotel and Conference Center
Salons 1–3
Tuesday, May 2
8:00 a.m.–4:30 p.m.

Join us at our preconference seminar, where SEL engineers will discuss specific topics related to power system protection, monitoring, control, communications, and integration. You will learn about the latest developments from SEL, such as high-performance time-domain line protection that securely and dramatically reduces relay tripping times. You’ll also hear about new, simple, secure SEL Time-Domain Link (TiDL) technology to modernize your substation. In addition, we will show you how to build fast, secure, and deterministic Ethernet communications networks for high-speed protection with game-changing software-defined networking (SDN) technology—and more!

The SEL seminar is complimentary and provides an excellent learning opportunity for beginners and advanced attendees alike. All attendees will receive 7.5 Professional Development Hours (PDHs) for attending (sent electronically the week following the event). Register for the SEL Technical Seminar today!
