TG105 – Mechanical & Electrical Fundamentals

TG105 – Mechanical & Electrical Fundamentals

Description

Skills typically required of a TG Field Engineer often include 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 course.  HPC instructs this course with experienced “TG Field Engineers or Mechanics” (often 30+ years of experience) who have the instructional skills as well.  Much of the course is lecture, but it includes efficient use of lab equipment in HPC facilities so that important tasks are demonstrated and practiced (as needed). Additionally, this 4-day course 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 course 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.

Objectives

At the completion of this course the participant will 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. List the advantages of mechanical seals
  10. Explain how mechanical seals work
  11. Demonstrate familiarity with Ohm's Law and the ability to apply this law in interpreting electrical circuits.
  12. Describe hazards associated with working with electricity and demonstrate how to protect oneself from this hazard.
  13. 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.
  14. Participants will have a working knowledge on how to properly select the function/range and connect a multimeter to measure current, resistance, and voltage.
  15. Demonstrate knowledge regarding the use and application of different types of electrical diagrams.
  16. Demonstrate knowledge as to what constitutes an Assured Equipment Grounding Program.
  17. Demonstrate operational knowledge and ability to use a Ground Fault Circuit Indicator (GFCI).
  18. Demonstrate a basic understanding of troubleshooting techniques involving branch and control circuits and the importance of the Lockout/Tagout concept.
  19. Demonstrate knowledge regarding the purpose of the National Electric Code (NEC).

Turbine Maintenance Certification

There are two levels of certification (Both levels require this course):
  1. Steam Turbine Field Engineer
  2. Steam Turbine Mechanical Technician
Those who attend this course are automatically qualified to take HPC Technical Services' Certification Examination.  This examination is offered at no additional expense to the participant.  An 80% passing grade is required.  The examination length will not exceed 2-hours.  Those who complete this examination will receive a revised "certificate of completion" that recognizes this accomplishment along with two-copies of a "To Whom It May Concern" letter that states their accomplishment.  (Two copies are provided, one for the participants' employer and one for the participants' personal file.)  Consult HPC's website, www.TurbineGeneratorTraining.com, for detail on this certification program.
