G706 - Advanced Generator Maintenance Seminar
|
|
3.5 days - 2.2 Continuing Education Units Awarded
When: January 19-22, 2009
Where: Lido Key (Sarasota), FL
$1795
This 3.5 day seminar was developed out of the recognition of the need for plant personnel to better cope with generator maintenance issues. In the total of 100+ years of experience of our presenters, we have seen too many major projects being undertaken that could have been avoided! Or too many plants have invested too many $$$ only to not realize a return due to the selection of the wrong materials, or to errors in reverse engineering, or not understanding the sequence of steps associated with a particular activity. It is the belief of all our presenters that we all gain by the presentation of this seminar (that is why they volunteered to make these presentations). The participant gains as he/she gains honest technical information. We gain as we know the participant will remember who provided this honest presentation when it comes time where outside engineering or training services are needed. We all benefit. Read more, and see you in Lido Key (Sarasota) FL in January 2009 (you missed our 2008 presentation).
Benefits :
- Learn to formulate better plan regarding quality stator testing & inspection schedules.
- Learn what to look for when conducting a visual inspection of the generator rotor and/or stator.
- Learn the purpose of conducting generator stator electrical tests, when they should (or should not) be conducted, and how to better evaluate the collected data.
- Generator lead boxes are need of testing too. Learn more about trouble areas in this area.
- Partial Discharge is the latest buzzword. Learn how it works, how to collect data, and what to do with the data collected.
- Stator re-wedging is a common major outage practice. Learn WHEN a re-wedge is needed and WHEN it is not. Also learn which wedges to use and what materials might be preferred (and why).
- Benefit directly from a couple case studies where the “expert” engineer walks personnel through the detection of a problem, analysis of that problem, troubleshooting, thinking through collected data, and an “after-the-fact” evaluation. Case studies include both the stator and the field.
- Learn the application of field electrical tests, when they should (or should not) be conducted, and how to better evaluate the collected data.
- Collector rings can be a source of operating problems. Specific visual and electrical tests may be performed to evaluate these rings. Learn the “thinking” behind these tests.
- Use of flux probes are significant in the industry. Learn why. Learn how the probe is installed and data is analyzed.
- Is your stator core loose? We will define the term “loose”, talk about how to determine looseness, and tightening methods. Learn also how to not make errors in timing of the work performed.
- Liquid cooled stator bars are another “hot” subject today. In this seminar you will learn the root cause, how to detect, how to evaluate, and what type of corrective actions may be needed, given the evaluation of the data collected.
- Generator Condition Monitors are an accepted instrument in large hydrogen cooled units. Learn how the instrument works, what can be done to ensure it continues to provide quality information to troubleshoot generator operational problems.
- Some generator problems are generated due to operational practices. These practices (where they have too often gone wrong) are discussed from both a theoretical and a practical aspect.
- There are a few vibration / balance issues that are peculiar to the generator. Learn what these are and how to recognize and evaluate the recorded data.
- The generator auxiliary systems can be the source of operational issues. Learn what they are and what many are doing to minimize the impact of these problems.
Why Attend This Seminar?
- Make better replace/repair/reuse decisions. This is a topic of discussion that continues throughout the 3.5-day seminar. Evaluation includes a thorough understanding of mechanical integrity, the selection and performance of electrical tests, evaluation of materials, and assembly.
- Get faulty equipment properly repaired. We've heard horror stories that include the performance of a complete rewind (at what cost?) only to experience short life of components due to the incorrect selection or installation of materials. In this seminar we address these issues. A complete rewind may OR may not be the correction action to take. It certainly is the easiest decision (from a technical perspective) and is, by far the most expensive. More, better technical evaluation might avoid a costly error.
- Perform and analyze generator electrical tests safely and effectively. What is the purpose of any single electrical test and when should it be performed? This is a major consideration. We discuss the value of each electrical test, the sequence that these tests should be performed (this is a major topic too often misunderstood).
- Manage generator repair projects to your benefit. Manage cost. Do so by writing quality contract (bid) specifications. Do so by selecting proper materials. Do so by carefully managing the environment under which the outage is performed. Do so by evaluating data. Do so by carefully analyzing all variables. In this seminar, experts discuss these topics and more.
Who Should Attend:
This seminar has been designed for Maintenance Superintendents, Supervisors, Engineers, and others with responsibility for generator maintenance. Attendance will provide the attendee with a thorough understanding of design, operations, and maintenance of generators. This seminar is for those who want serious discussion of their generating units!
In our first seminar (July 2003) one of the participants, an engineer from a nuclear power plant in the Midwest, made a statement that this investment saved him (his company) hundreds of thousands of dollars! Why? He learned how to avoid a major error that may have otherwise been made. He learned one significant item and the payoff could be phenomenal. This is the type of person we hope attends this seminar.
