Have you ever seen relay protection performance that eliminates relay operating times, clears faults in breaker operating times, and locates faults within one tower span? This type of performance is not only possible but field-proven using the SEL-T400L Time-Domain Line Protection.
This recorded webinar focuses on ultra-high-speed protection using SEL’s time-domain technology based on traveling waves and incremental quantities. Its functionality includes the underreaching incremental-quantity distance protection element (TD21), permissive overreaching transfer trip logic with traveling-wave (TW32) and incremental-quantity (TD32) directional elements, and the traveling-wave differential protection scheme (TW87).
