Note: As a prerequisite, participants should have prior knowledge of circuit breaker application basics and associated IEC or IEEE standards.
The principal cases of interest are the interruption of the currents associated with terminal faults, short line faults and out-of-phase switching and breaking capacitive and inductive load currents. The seminar discusses each case in detail and explains the origin and derivation of the attributes associated with the TRVs including pole factors, amplitude factors, two and four parameter representations and travelling waves where applicable.

Seminar Description

Transient recovery voltages (TRVs) are the voltages imposed on circuit breakers immediately after current interruption. TRVs generally have a power frequency component and an oscillatory component dependent on the circuit and the type of current being interrupted. The principal cases of interest are the interruption of the currents associated with terminal faults, short line faults and out-of-phase switching and breaking capacitive and inductive load currents. The seminar discusses each case in detail and explains the origin and derivation of the attributes associated with the TRVs including pole factors, amplitude factors, two and four parameter representations and travelling waves where applicable. The approaches taken in the IEC and IEEE standards will be discussed with particular reference to type testing. The seminar is hands-on, please bring a calculator to the session.

Presenter 

Dr. David Peelo, P.Eng, C.Eng, FIEE D.F. Peelo & Associates Ltd.

Dr. David Peelo is a consultant and former switching specialist at BC Hydro.
 
He is a graduate of University College Dublin and Eindhoven University of Technology. He worked first at the ASEA Power Transmission Products Division in Ludvika, Sweden and then for BC Hydro for 28 years rising to the position of Specialist Engineer.
 
As a consultant, he has clients worldwide and in particular teaches continuing professional development courses on current interruption transients and surge arrester application. He is an active IEEE and Cigre member and is a past Convenor of IEC MT32 (Inductive load switching), the Convener of IEC PT42 (Current interrupting capability of air break disconnectors) and a member of IEC MT57 (Application guide for IEC 62271 100 and other circuit breaker related standards). He is an IEC 1906 Award recipient and a Distinguished Member of Cigre. He has authored or co-authored over 70 papers on circuit breakers and surge arrester application, is the author of a textbook on current interruption transients calculation and a co-author of a textbook on switching in transmission and distribution networks.
