CT514 - (GE) Mk-II Gas Turbine Controls

5 days - 3.2 Continuing Education Units Awarded

Learn the operations, maintenance and troubleshooting techniques on this control system in a classroom environment as opposed to 2pm Friday afternoon when the demand is high and the unit won't start.

This course is intended for E/I Technicians, Engineers and Operators.

OBJECTIVES
Upon successful completion of this course the participant should be able to:

1. Competently use the GE Mk-II drawings/schematics normally available on the job-site.
2. Thoroughly understand the print and identification numbering system used throughout the turbine control system.
3. Trace out the electrical signals throughout the control system.
4. Understand the basic theory used with summing devices.
5. Understand the hydraulic servo-mechanisms.
6. Given a normal change in operating conditions, describe the proper response of the control system and the response of the individual components.
7. Understand the appropriate calibration procedures.
8. Understand troubleshooting sequences peculiar to this control system.
9. Communicate control problems in a more effective manner.
