Session 1:  Vacuum Circuit Breaker Switching Transients


Switching transients associated with circuit breakers have been observed for many years.  Recently this phenomenon has been attributed to a significant number of transformer failures involving primary circuit breaker switching.  These transformer failures had common contributing factors such as 1) primary vacuum or SF-6 breaker, 2) short cable or bus connection to transformer, and 3) application involving dry-type or cast coil transformers and some liquid filled.  This paper will review these recent transformer failures due to primary circuit breaker switching transients to show the severity of damage caused by the voltage surge and discuss the common contributing factors.  Next, switching transient simulations in the electromagnetic transients program (EMTP) will give case studies which illustrate how breaker characteristics of current chopping and re-strike combine with critical circuit characteristics to cause transformer failure.  Design and installation considerations will be addressed, especially the challenges of retrofitting a snubber to an existing facility with limited space. Finally, several techniques and equipment that have proven to successfully mitigate the breaker switching transients will be presented including surge arresters, surge capacitors, snubbers and these in combination.


Speaker:  Dave D. Shipp, PE, (S’72-M’72-SM’92-F’02)


Dave received the B.S.E.E. degree from The Oregon State University, Corvallis, Oregon, in 1972.  He is a Principal Engineer for Eaton Corporation’s Electrical Services and Systems Division and a Fellow Engineer in the Institute of Electrical and Electronic Engineers (IEEE).  He is a distinguished scholar in power system analysis and has worked in a wide variety of industries.  Over the last few years, he has pioneered the design and application of arc-flash solutions, modifying power systems to greatly reduce incident energy exposure. Present day topics cover switching transient induced failures of transformers.  He has written over 85 technical papers on power system analysis topics. More than 12 technical papers have been published in IEEE/IAS national magazines and two in EC&M. He spent ten years as a professional instructor, teaching full time. He occasionally serves as a legal expert witness with a specialty in forensics (failure analysis). Mr. Shipp is currently the Chair for the IEEE I&CPS-sponsored Working Group on generator grounding. He has received an Industry Applications Society (IAS)/IEEE Prize Paper Award for one of his papers and conference prize paper awards for six others. He received the 2011 IEEE Richard H. Kaufmann award.  He is very active in IEEE at the national level and helps write the IEEE Color Book series standards.

Speaker:  Jim Phillips, PE -  Founder, Brainfiller


Jim is a Registered Professional Engineer and his experience includes everything from planning transmission systems, to design and analysis of industrial, commercial and utility power systems, cogeneration plant design, expert witness and forensic analysis.   In 1987, Jim began his training company, Brainfiller.com. He has developed over 25 different training programs ranging from protective relaying to various power system analysis topics, grounding, arc flash studies, NEC®, NFPA 70E® and more. He has written numerous articles about electrical power systems and has a regular column about arc flash and electrical safety for Electrical Contractor Magazine. He has also written several articles that have been published in Europe and created the internationally known website: ArcFlashForum.com.   


Jim is a member of the IEEE P1584 IEEE Guide for Performing Arc-Flash Hazard Calculations, Vice-Chairman of IEEE 1584.1, Guide for the Specification of Scope and Deliverable Requirements for an Arc-Flash Hazard Calculation Study in Accordance with IEEE 1584, a member of ASTM F18 Electrical Protective Equipment for Workers, is a representative of the United States for the International Electrotechnical Commission (IEC) TC 78 Live Working, and IEC 61482-1-2 “Box Test Method” as well as many other national and international committees and organizations. 


Jim earned a BSEE Degree in Electrical Engineering from the Ohio State. His career began with Square D Company’s Power System Analysis Group where he was responsible for power system studies, software development and training at their engineering training. Later, Jim was with Ohio Edison Company where he performed transmission planning studies and then headed up the short circuit studies group. 


Session 3:  Motor Acceleration & Transient Stability – Load Shedding


Motor Acceleration:  This presentation will cover basics of how an induction motor works and its fundamental components. A discussion on the motor construction and type (i.e. NEMA MG-1 Design letters) and its influence on the acceleration time, acceleration torque and load will also be presented. The modeling approaches (static vs. dynamic) will be presented using practical applications to help the engineer select the correct motor starting analysis.  Different types of motor starting schemes including variable or adjustable speed drive applications will be compared. The presentation will also discuss some practical issues like the impact of the number of motor starts (depending on the type of motor design), load profile selection (i.e. reciprocating or cyclic loads) and the impact of the motor acceleration process in the selection and sizing of the motor.


Transient Stability:  This presentation will discuss the conventional methods of system load shedding and provide guidelines on how to determine the correct amount of load to be shed to prevent system instability. This presentation will also cover the basics of system frequency control, the impact of exciters and governors on the load shedding schemes and the different load shedding schemes like breaker interlocks, under frequency relays and PLC based load shedding. An introduction to modeling and data preparation and transient stability study outputs will precede this presentation to provide some fundamental background.


Speaker:  Hugo Albert Marroquin, BScEE, PE – V.P., Validation & Verification,



Mr. Albert Marroquin is a registered professional engineer in the state of California.  He is the product manager for ETAP’s User-Defined Dynamic Modeling Program. In this area, Mr. Marroquin has gained expertise in modeling exciters, governors, power system stabilizers and general system dynamics including motor acceleration and general dynamic system models. He is also the main designer and product manager for ETAP’s Arc Flash program as well as a working group member of IEEE 1584, IEEE 1458 and an active contributor to NFPA 70E committees.  He has recently become a working group member of IEEE P1814™/D1 (Draft Recommended Practice for Electrical System Design Techniques to Improve Electrical Safety). 


Albert joined Operation Technology, Inc (ETAP) in January 2001 as an Electrical Engineer; his current position with ETAP is Vice President of Validation and Verification. In this position, he is responsible for overseeing the validation and verification of most ETAP modules.  He has expertise in the guidelines and standards for several areas including Load Flow, Short-Circuit (ANSI and IEC), Arc Flash, Transient Stability and DC Systems.  The V&V of the results for the majority of ETAP modules and the supervision of several electrical engineers also fall under his responsibilities. He is also an advanced power system modeling instructor for the ETAP training program.


Session 4: 

Q & A With Your Favorite Electrical Equipment Supplier Reps.


For the previous two IEEE Seminars, the four “Fixtures” from GE, Eaton, IEM, and Schneider Electric have reviewed power distribution equipment basics, and discussed specifications.  This year, the Reps. will stand before the seminar attendees with blank easels, some easy to read markers, and with any luck, answers to your questions.  So, bring some hard questions pertaining to electrical distribution equipment, products and applications, codes and standards, and we will do our best to address industry issues and concerns.
