FRIDAY FEATURE PRESENTATIONS
 
Kris Nielson, Pegasus-Global, Cle Elum, WA
The events at the Fukushima complex following the 2011 earthquake and tsunami resulted in international concerns about nuclear power.  This lecture will discuss the event, public reactions, and explore what it means for the nuclear power industry. 
 
Event Analysis for Relay Techs
Charlie Wagner, PacifiCorp, Klamath Falls, OR
Often what appears to be a legitimate fault trip or even a misoperation may not be so, and a good investigation requires correlating multiple sources of data and information from all of the tools at a technician's disposal.  This lecture will use real occurrences and interesting situations to demonstrate how an experienced tech investigates, analyzes, and evaluates an event. 
OPEN CONCURRENT LECTURES
The Hands-On Relay School offers twelve lectures on a wide range of topics relevant to the trade.  Each lecture is one hour long and given a total of three times.  Students can attend up to six of the lectures of their choosing.
 
Application and Testing of Substation Control Circuitry
Greg Butler, BPA, Port Angeles, WA
A relay is only as good as its wiring. This lecture presents an overview of typical AC and DC substation control wiring components and practices, physical and functional verification testing, maintenance practices, common problems, and troubleshooting tips. 

Breaker Failure Protection          Part 2
Brent Carper, Relay Application Innovation, Inc. (RAI), Pullman, WA
This lecture will review different types of breaker failure protection systems, relays, and logic, including general considerations for determining relay pickup and timing settings.

CT Saturation and Residual Magnetism
Will Knapek, OMICRON, Adams, TN
High fault currents or DC components can saturate current transformers and result in residual magnetism left in the CT.  This lecture will explore this phenomenon and the consequences of residual magnetism. Techniques of how to measure residual magnetism will also be discussed. 

Dynamic Relay Testing     Part 2
Tony Giuliante, ATG Consulting, Galloway   NJ
Dynamic testing is an alternative system testing technique that provides advantages over traditional steady state calibration of individual relay functions.  This approach eliminates common testing problems and provides better understanding of relay design and operation.

End to End Testing
Chris Werstiuk, Manta Test Systems, Mississauga, ON
End-to-end testing is considered the ultimate test for any protective relay scheme using communications and can seem like a daunting task. This lecture will provide a step-by step introduction of a typical end-to-end test to demystify the process.

Fundamentals of Bus Protection
Kevin Wright, SMUD, Sacramento, CA
Bus protection comes in many different forms including high impedance or low impedance differential, overcurrent, distance, linear coupler, trip blocking schemes, and communication-based schemes.  This lecture will provide an overview of the different types of bus protection and the advantages and disadvantages of each.

NERC PRC-005 Standard
Eric Udren, Quanta Technology, Pittsburgh, PA
The NERC Drafting Team has just developed the new PRC-005-2 Protection System Maintenance Standard, with specific requirements for maintenance activities and maximum time intervals.  This lecture will discuss the new requirements and also new options for system maintenance programs.

Phasor Diagrams         Part 2
Ron Alexander, Bonneville Power Administration, Salem, OR
Phasors are the universal language of system protection technicians and engineers. This lecture emphasizes the need for a basic knowledge of phasor diagrams and their use in understanding the power system. Topics include load flow phasor analysis, fault phasor analysis, and using phasors to determine the phase angle across delta-wye transformer banks.

Symmetrical Components 1 & 2
Stephen Marx, Bonneville Power Admin, Malin, OR
Part 1: Symmetrical components with explanation of phasors, per unit system, and basic symmetrical component equations using sequence networks. 
Part 2: Analysis of power system elements with symmetrical components network and network connections for each power system fault type. Samples of protective relay applications using symmetrical component method.

Testing Microprocessor Relays
Chris Werstiuk, Manta Test Systems, Mississauga, ON
Microprocessor relays are far more complex than previous generations of protective relays, but many of us still use the same old test procedures designed for variacs and phase shifters. This lecture discusses how to use modern test equipment and techniques for more effective and efficient relay testing.

Transformer Protection
Scott Cooper, Manta Test Systems, St. Petersburg, FL
An overview of power transformer protection practices. Emphasis is placed on solutions to the challenges of effective protection including transformation ratio, transformer connection, current transformer connections, zero sequence current elimination, inrush, and over excitation. Analysis of differential relay operation for various types of faults and fault locations is discussed.
