Performance of Time-Domain Protection on Real-World Faults

Date held: June 15, 2016

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:

  • An incremental quantity distance element
  • An incremental quantity directional element
  • A traveling wave directional element
  • A traveling wave line current differential element

In this webinar, the presenter will review time-domain line protection elements and illustrate their operation performance using real-world faults and digital simulations.
