G404 – Generator Protection

G404 – Generator Protection

4.5 days - 32 PDH Credits Awarded



At the completion of this course, the participant will be able review, analyze, and make better decisions regarding generatorprotection. All discussions will be conducted to balance generator protection against inadvertent separation.

Course Objectives

Upon completion of this course, the participant should be able to:
  1. Demonstrate the ability to interpret generator one-line diagrams.
  2. Describe the concept of zone protection.
  3. Describe the use of current and potential transformers used in protective relaying schemes.
  4. Describe how a generator is at risk in fault-like conditions, to include:
    1. Stator Ground
    2. Stator Phase-to-Phase
    3. Reverse Power
    4. Voltage/Frequency
    5. Phase Over-Current
    6. Negative Phase Sequence Current
    7. Inadvertent Energization
    8. Field Ground
    9. Loss of Synchronism
    10. Loss of Excitation
    11. Overspeed
  5. Describe how conditions might be monitored to detect those generator conditions listed above.
  6. Describe typical protective relay concepts that are employed to provide generator protection against those events described above.
  7. Describe considerations to be used in determining settings and action of protective relays.

Frequently Asked Questions

  • Will HPC Technical Services bring this course to our location for our personnel only? YES, call or Stephen Parker, Stephen@TurbineGeneratorTraining.com for a price quotation.  Please note, however, you need to have lab facilities.  Our equipment can be transported or labs can be set up with available equipment on-site.
  • Will HPC Technical Services customize the presentation at our site to suit our particular needs?
  • Is HPC Technical Services' textbook available for purchase as a reference document?
  • What is the cost for HPC Technical Service to deliver this course at our location? Well, of course that can vary, but generally speaking, if you're planning on having 6+ attend, when considering your T&L, it is to your advantage to perform the course at your plant (office).  You gain from the customization and price.
  • Can HPC Technical Services provide "Technical Assistance" in the planning and implementation of our outages? Yes we can.  Call or contact Stephen Parker, Stephen@TurbineGeneratorTraining.com for our rate sheets and any further information required.

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.
