Time-domain protection principles break the speed barrier that is imposed by today’s phasor-based line protection principles. Using transient voltage and current information dramatically reduces transmission line protection operating times from 1–1.5 cycles to 1–4 milliseconds.
The new SEL-T400L Time-Domain Line Protection applies the following to achieve fast and secure protection:
In this webinar, the presenter will review time-domain line protection elements and illustrate their operation performance using real-world faults and digital simulations.
