This course will begin by exploring the historical perspective of interrupters such as airmagnetic interrupters and oil interrupters and will then move into the current day use of the vacuum interrupter technology. Course will delve into the important characteristics of vacuum interrupters and the associated factory tests: contact resistance test, high potential test and the leak rate (MAC) test. Day 1 RTS Basic Track The RTS Basic track provides a chance to get up-to-speed in a hurry. Technicians and engineers who are new to relay testing that need to learn the basics behind what RTS does and get proficient with using RTS will want to attend this course. Attendees should bring his/her laptop with RTS installed. Day 2 RTS Advanced Track The RTS interface is built entirely for test manipulation. In this class, attendees will be exposed to all of the numerous tools and techniques available for creating or customizing any test routine. Moving beyond test plan modification, attendees will learn about RTS commands and gain insights that will be useful as they develop new test routines of their own. Attendees should bring his/her laptop with RTS installed. Day 3 RTS Dynamic Testing ENOSERV Vector is now a part of ENOSERV RTS 7 (and not a separate product). Learn how to enable satellite-synchronized end-to-end relay testing, prove fault isolation schemes, and user-defined logic. Attendees should bring his/her laptop with RTS installed. Day 1 Fundamentals of Protection

6 This course will touch on the basics of power system protection. Attendees will learn about the hardware components in a power system and protection methods applied to them. Attendees will learn how to read and interpret the system design documentation required to develop relay settings. Finally, students will learn how apply real time measurements, event records and waveform captures to troubleshooting and commissioning. Day 2 Differential Protection This course will cover all differential protection applications. Students will learn the basic configuration of bus differential relays(emphasis on B30, B90), transformer differential protection (emphasis on T35/T60), line differential protection (emphasis on L30/L90), generator and motor stator differential protection (emphasis on G60/M60). Day 3 Protection & Control Using Advanced Communications Attendees will be introduced to Direct I/O and the IEC standard, including GE s Hard Fiber. Attendees will learn how relays equipped with these capabilities can be applied to auto transfer schemes, zone selective interlocking schemes, transfer tripping, and more. The final two hours will be dedicated for Q&A time on any topic from any of the three sessions. Day 2 Transformer Maintenance Advanced Testing Techniques and Analysis: 4 hours The majority of tests performed on power transformers today have the same goal to determine the overall condition of the electrical, mechanical and dielectric components. This segment will focus on getting you up to date on the latest methods and technologies available for electromechanical and insulation diagnostics. This series of lectures will cover advanced analysis techniques for accurately assessing temperature compensation, voltage dependency, moisture vs. contamination, and mechanical stress in transformers. Throughout the seminar, the theoretical fundamentals of power factor, dielectric frequency response, and sweep frequency response analysis will be explained and discussed and emphasis will be done on the technical references and standards recently published for interpretation of advanced diagnostics methods such as SFRA and DFR. Practical application of the techniques will be illustrated through real life case studies. Hands on Transformer Testing: 4 hours

7 Attendees will get the opportunity to participate in the different activities to operate the testing equipment and analyze results from power factor, dielectric frequency response, and sweep frequency response analysis. This practical session will simulate the real world conditions so attendees can get a better understanding of transformer testing under ideal and real conditions. Test equipment used will include Megger s Delta 4310, FRAX101, and IDAX300. Day 3 CT & Relay Maintenance CT Testing and Analysis: 4 hours Current Transformers (CT) play an important role in power systems for metering and protection applications. This segment will cover test procedures found in the IEEE Guide for Field Testing of Relaying Current Transformers. This seminar will cover the technical reason to perform tests such as saturation, insulation resistance, ratio and polarity and excitation, and the flaws they help to uncover in CTs. There will also be detailed discussions on how to analyze and interpret the results of each test. Test equipment used will include Megger s MRCT. Transformer Differential Testing Techniques: 4 hours In the past we could test electromechanical transformer differential relays one phase at a time with little to no worry about undesirable operation of the scheme. With the advent of microprocessor relays it is becoming more difficult to arrive at this result. Three phase element based testing is becoming more prevalent due to the fact that the newer generation of relays has become smarter over the years. One other great advantage of three phase testing is it is one of the few ways to detect settings errors that can operate the differential element for external through faults. We will discuss the advantages of testing the relays as a scheme and examine the results of the total relay operation as a whole. Also, we will cover a few examples of case studies where single phase testing was done and the relay operated for external faults. Day 1 Introduction to SEL Relays Engineers and technicians new to SEL relays will benefit from this class. The instructor will demonstrate the use of the SEL 751A Feeder Protection Relay to learn the basics of acselerator QuickSet SEL 5030

8 Software, how to write SELogic control equations, and how to do basic testing. Students will convert control schematics and settings for an electromechanical relay into SEL settings and SELogic control equations, and create an acselerator settings file for the relay. Students should bring their own laptops with acselerator QuickSet SEL 5030 Software (including SEL 751A drivers) and acselerator Analytic Assistant SEL 5601 Software installed prior to class. Day 2 Fundamentals and Advancements in Transformer Differential Protection Students will develop transformer protection settings using an example transformer nameplate and connections. Students will learn about the differences and advancements in transformer protection, including raw differential quantities, adaptive slope operation, and the negative sequence differential element. Students will calculate basic test points for their settings. The instructor will demonstrate basic differential pick up, slope 1 and slope 2 differential tests. Students will analyze real world examples of settings and wiring errors to emphasize the importance of correct transformer differential settings and proper testing. Students should bring their own laptops with the latest acselerator QuickSet SEL 5030 Software version (including drivers) installed prior to coming to class. Day 3 Event Analysis Becoming proficient in analyzing relay event reports is key to performing testing, understanding fault data, determining root cause, and improving reliability. This class will teach students who are new to event analysis about what types of event data are available from relays, how to use acselerator Analytic Assistant SEL-5601 Software, how to methodically perform event analysis, and how to document their findings. Students will analyze basic real-world event data with their laptops in order to understand fundamentals. Students should bring their own laptops with acselerator Analytic Assistant SEL-5601 Software installed prior to class.
