Description

One of our leading consultants has stated numerous times that the transformer is the “heartbeat” of the grid.  Without the transformers we will deliver no power to our customers at all.  In this course we will learn how a transformer operates and how it is usually safeguarded.  One means of safeguarding transformer operation there is a need to not exceed nameplate ratings and we need to interpret this nameplate data.  Next we need to fully appreciate the insulation it is tested.  The current, of course generates a tremendous amount of heat, and participants will learn what are the limitations, what are the means of cooling, and how to recognize trouble.  Once a participant fully appreciates how the transformer functions, and how it is protected, one can better understand and apply preventive maintenance procedures. This course covers the theory, operation, maintenance and testing of power transformers and auxiliary equipment. Topics included are transformer fundamentals, transformer ratings, transformer cooling, nitrogen gas systems, insulation systems, maintenance activities. The course concludes with in-depth discussions on transformer testing techniques. This course is applicable to technicians and engineers who need a sound understanding of power transformer operation and maintenance.

Objectives

Upon completion of this course, the participant should be able to:
  1. Describe transformer operation and simple theory.
  2. Demonstrate understanding of transformer nameplate data.
  3. Describe the different types of transformer construction and designs
  4. Understand the concept that insulation is the "heart of the transformer" and thus maintenance efforts are for its preservation
  5. Describe how normal and abnormal operating conditions affect the transformer reliability.
  6. Demonstrate knowledge of procedures to prevent early failure and/or extending life
  7. Describe obstacles to reliability/availability of transformers, to include; Moisture, Heat, Forces, Voltage stress, Oxygen and Contamination
  8. Describe different maintenance methods.
  9. Describe maintenance testing and evaluation methods.
  10. Demonstrate ability to apply knowledge gained, to actual transformer maintenance activities.
