New SEL book shares latest in ultra-high-speed fault detection, location technology

Time-Domain BookSEL has released a new book that explains the latest innovations in using traveling waves and instantaneous incremental quantities for ultra-high-speed line protection and fault locating. The book is a compilation of 15 technical papers on applying time-domain technology.

Locating Faults and Protecting Lines at the Speed of Light addresses the use of traveling waves and instantaneous incremental quantities for line protection. It also covers traveling wave-based fault locating. The book is composed of technical papers written by research and development engineers, field application engineers, and protection practitioners from several companies and is edited by Edmund O Schweitzer, III; Bogdan Kasztenny; Armando Guzmán; Venkat Mynam; and Héctor J. Altuve Ferrer.

Accommodating load growth with limited investments has eroded electric power system reserve margins in recent decades. New renewable sources are variable, more difficult to dispatch, and have very little inertia. As a result, today’s power systems operate close to their security limits and require fast fault clearing and accurate and timely fault locating. Time-domain technology allows relays to respond to traveling waves and instantaneous incremental quantities. Such relays significantly improve line protection operating speed and fault-locating accuracy.
 
The book is available for purchase in the SEL bookstore.
