DESCRIPTION:[What is Travelling Wave? Definition\, Specification & Travelli
 ng wave on  Transmission Line - Circuit Globe]\n\nAbstract: This presentat
 ion is a brief overview of transmission line protection using time-domain 
 principles\, including an introduction to traveling waves (TWs) and increm
 ental quantities that are produced when faults occur in electric power tra
 nsmission systems. Ultra-High-Speed (UHS) line relays include TW-based and
  incremental-quantity-based protection elements and schemes with operating
  times of 1 to 5 milliseconds. This substantial reduction in relay trip ti
 me is needed for protecting today’s power system transmission lines near
  non- standard sources\, such as wind turbine generators or inverter-based
  sources\, in low-inertia systems with HVDC links\, and in systems with se
 ries compensation. UHS relays also include TW-based fault locating (TWFL) 
 methods to locate faults with a high level of accuracy and to perform cont
 inuous line monitoring. The ability of UHS relays to provide fault recordi
 ng at a 1MHz sampling rate and 18-bit resolution allows analysis of high-f
 requency power system events\, including breaker reignition and breaker tr
 ansient recovery voltages. Transient records with 1 MHz sampling will be u
 sed to demonstrate the performance of UHS line protection\, visualize the 
 results of the double-ended TWFL method by showing the time-\nspace relati
 onship of TWs on a Bewley lattice diagram\, and present post-fault arcing 
 and circuit breaker reignition observed during the fault event.\n\nCo-spon
