Description

This is one of those systems that can run for seemingly, forever.  Then there is that “one-day”.  We all remember that one-day. That is the day you may wish you (or one of your plant's technicians/engineers) had attended this course.  If something has gone wrong then attention is going to be completely focused on you, assuming you are responsible for your AlterrexTM system.  Equipment-experienced engineers present the course.  Simply put, the overall objective of this (GE) AlterrexTM  This Excitation System Training Program is to develop the individuals responsible for plant operations, testing, calibration and maintenance of this system.  To accomplish we have a need to understand the “big-picture”, to understand the OEM print systems, to understand how to read those prints and maintenance instructions, and finally, we need to understand how to apply this knowledge toward the solution of operating problems. A topical outline for this course will include:  Generator Characteristics and Design Features, Operation of an Automatic Voltage Regulator, Excitation System Components,  Alternator Field Control, AC Regulator, Protective Features, Station One Line Diagram, Print Interpretation and Drawing Practices, Excitation System Alignment Procedures, Troubleshooting Tips, Techniques and Industry Examples This course is designed for Engineers, Technicians, and Electricians who have a need to maintain this system.

Objectives

Upon completion of this course, participants will be able to:
  1. Learn how the AlterrexTM Excitation System works.
  2. Learn the location and purpose of the major components that make up the AlterrexTM Excitation System.
  3. Learn to interpret alarms and know what corrective action is needed to take in the event of an alarm.
  4. Learn to perform recommended operational tests.
  5. Learn to perform periodical maintenance on the AlterrexTM Excitation System.
  6. Learn to accurately calibrate the AlterrexTM Excitation System utilizing the necessary OEM drawings.
  7. Learn to quickly and safely troubleshoot the AlterrexTM Excitation System if a problem should occur or a component fail within the system.
