Description

This 4 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 at the next seminar.

Objectives

1. Visual Inspections: Learn what to look for when conducting a visual inspection of the generator stator and rotors.
2. Electrical Tests: Learn the purpose of conducting various generator stator/rotor electrical tests, when they should (or should not) beconducted, and how to better evaluate the collected data.
3. Stator Re-Wedge: Learn how to determine when stator re-wedge is needed, as well as which wedges to use and what wedge materials mightbe preferred (and why).
4. vStator Core Looseness: Learn how to determine if your stator core is loose, when the tests are to be performed, and how to tighten.
5. Liquid Cooled Stator Bars: Learn to evaluate liquid cooled stator bar data, determine the root cause, how to detect, how to evaluate, andwhat type of corrective actions may be needed, given the evaluation of the data collected.
6. Generator Lead Boxes: Learn about trouble areas in the generator lead boxes and tests to be performed.
7. Collector Rings: Learn how collector rings can be a source of operating problems and how specific visual and electrical tests may beperformed to evaluate these rings.
8. Flux Probe: Learn the purpose of the flux probe, how the flux probe is installed, how data is collected and analyzed.
9. Partial Discharge Analysis: Learn how Partial Discharge works, how to collect data, and what to do with the data collected.
10. Operational Practices: Some generator problems are generated due to operational practices. These practices (where they have too often gonewrong) are discussed from both a theoretical and a practical aspect.
11. Generator Vibration: There are a few vibration / balance issues that are peculiar to the generator. Learn what these are and how to recognizeand evaluate the recorded data.
12. Generator Diagnosis with Electromagnetic Interference (EMI): learn the benefits and technology of EMI and how it can help identifyupcoming outage planning needs.
13. Generator Operational Events: Given a major generator event, learn the major risks associated with those events, relay actions, things toinvestigate, and actions to take.

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. Learn one significant item and the payoff could be phenomenal. This is the type of person we hope attends this seminar.

Why attend this seminar?

Make better replace/repair/reuse decisions. This is a topic of discussion that continues throughout the 4-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.
