An important part of any maintenance outage includes rigging (directly and indirectly) and lifting heavy equipment.   It is very important that the TG Field Engineer be familiar with principles associated with rigging and lifting heavy equipment of the type typically found on turbine-generator installations.  Furthermore, the use of precision measuring equipment to determine equipment condition is another important skill.  TG Engineers (and mechanical technicians) are typically in a role where they must plan, supervise and evaluate these outages skills as they are implemented.  These skills are learned in this Seminar.  HPC instructs this Seminar with experienced “TG Field Engineers or Mechanics” (often 30+ years experience) who have the instructional skills as well.  Much of the Seminar is lecture, but it includes efficient use of lab equipment in HPC facilities so that important tasks are demonstrated and practiced (as needed). Paramount to a successful maintenance outage is the evaluation of the condition of turbine-generator components.  One of the most effective ways to accomplish this is with a thorough non-destructive examination (NDE) of those components.  Understanding how these NDE examinations are conducted and how to evaluate the results is another part of the successful TG Field Engineers training.   Skills typically required of a TG Field Engineer include the planning and scheduling of turbine-generator maintenance outages.  It is imperative that a “plan” be devised and that plan “followed” to ensure successful, on-time completion of a maintenance outage.
Additionally, this Seminar will discuss how to ensure a safe working relationship with electricity that involves activities that do not require a master electrician.  These include, but not limited to:
  • how to read an electrical schematic;
  • how to measure circuit parameters (voltage, current, and resistance);
  • how to perform systematic troubleshooting; and
  • how to properly size a wire for a given application along with its proper termination at the device and the breaker box.
Also, this Seminar explains what constitutes an Assured Equipment Grounding Program, which comprises of describing the operation of a Ground Fault Circuit Indicator (GFCI) along with knowing when one is required at the workplace; and explicates the benefits of an Electrical Maintenance Planning Program.
Upon successful completion of this Seminar the participant should be able to:
  1. Identify and describe those lifting devices and/or fixtures commonly used in the lifting of TG components
  2. Correctly choose the lifting equipment required for the safe and efficient lift of an assigned job task that involves a lifting procedure
  3. Visually inspect lifting devices used in the normal daily routine as they pertain to maintenance activities
  4. Select and use the proper precision measuring instruments for the assigned task
  5. Accurately measure equipment parts to determine their continued usefulness or warranted replacement
  6. Accurately set up, check and record the total indictor run out on a rotating element or shaft assembly
  7. Take and record mechanical sizes and conditions as they pertain to the manufacture of replacement parts
  8. Properly care for and store precision measuring instruments thus ensuring their readiness for and ability to take the next set of accurate readings
  9. Describe the common procedures for cleaning and prepping components for inspection
  10. List and describe the various non-destructive examinations that can be performed as part of a component inspection
  11. Describe the criteria used to evaluate defects found during component inspection
  12. Demonstrate familiarity with Ohm's Law and the ability to apply this law in interpreting electrical circuits
  13. Describe hazards associated with working with electricity and demonstrate how to protect oneself from this hazard
  14. Demonstrate a working knowledge of the functionality of a multimeter, voltage testers, a non-intrusive ammeter; and identify the instrument that is used to verify the integrity of wire insulation
  15. Participants will have a working knowledge on how to properly select the function/range and connect a multimeter to measure current, resistance, and voltage
  16. Demonstrate knowledge regarding the use and application of different types of electrical diagrams
  17. Demonstrate knowledge as to what constitutes an Assured Equipment Grounding Program
  18. Demonstrate operational knowledge and ability to use a Ground Fault Circuit Indicator (GFCI)
  19. Demonstrate a basic understanding of troubleshooting techniques involving branch and control circuits and the importance of the Lockout/Tagout concept
  20. Demonstrate knowledge regarding the purpose of the National Electric Code (NEC)
  21. List operational and safety issues that typically cause the scheduling of a maintenance outage
  22. List the considerations that must be included when developing an outage plan or schedule
  23. Describe the major considerations when making a replace/reuse/repair decision.
