Letter From the President SCHWEITZER ENGINEERING LABORATORIES LETTER FROM THE PRESIDENT SPEED AND SECURITY, AND SECURITY To minimize risks to people, property, and power systems, we need to clear and isolate faults as fast as possible. The SEL-T400L Time-Domain Line Protection breaks the “speed limit” imposed by phasor concepts. Its time-domain and traveling-wave principles deliver speeds 4–10 times faster than phasor-based protection. And, it’s secure. It’s no good to be fast and wrong. The SEL-T400L is fast and RIGHT! We’re beginning to see transmission and distribution through a new...
