2 days - 14 PDH Credits Awarded

$1,695.00

Description

There are NO SMALL PROBLEMS when it comes to your GENERATOR!!  Be prepared for your next outage.  Make sure you fully understand Safety, Testing, Inspection/Repair as well as disassembly/reassembly.  Don't be surprised.  Be prepared.  Register for this course today.  This course is designed for plant engineers who have a specific need to better understand generator equipment.  Plant electrical and mechanical maintenance technician’s benefit as well.
  • Corona discharge, what does that mean?
  • How do you repair fused stator punchings?
  • What components should be high potential tested?
  • How can we avoid accidental injury when testing the generator?
  • What are the probable causes of grounded fields?
  • ...And the list of answered questions goes on!!

Objectives

Upon completion of this course, participants will be able to:
  1. Describe the major activities associated with generator maintenance.
  2. Describe proper generator disassembly and reassembly sequences.
  3. Describe the procedures for cleaning generator components.
  4. Describe the procedures for inspection of generator components.
  5. Given any generator component, describe the types of damage that might be found, and what are probable causes of that damage.
  6. Describe the various repair methods for defective component condition.
  7. List all those electrical tests commonly performed on large AC generators.
  8. For each electrical test listed, describe the purpose of conducting that test; i.e., what are we looking for as a result of the test?
  9. Describe the procedures for the various generator tests.
  10. List and describe safety precautions for the conducting of these electrical tests.

What you will receive

  1. 1 copy of HPC Technical Services' textbook, Generator Maintenance, a $219 value, as written by Harold Parker, with technical support by via HPC's Advanced Generator Maintenance Seminar personnel, primarily AGT Services. This text contains a significant number of equipment photographs, graphics and data tables.  It is a valuable desktop reference in addition to being able to enhance the learning process.
  2. A Certificate of Completion with 14 PDH
Generator Maintenance Certification There are three levels of certification (All levels require this course):
  1. Engineer
  2. Mechanical Maintenance Technician
  3. Electrical Maintenance 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.
