Power Transformer Testing

COURSE NO: E03-041
Power Transformer Testing
Course Highlights

This online engineering PDH course provides information on the power transformer testing procedures, standards and the latest industry practices. It also includes details on online condition monitoring assessment of transformers and bushings and lighting arresters.


Transformers may be tested using AC or DC voltage. AC voltage is preferable to DC voltage for transformer testing because AC voltage simulates the internal stress that the transformers face during operating conditions.


This 3 PDH online course is suitable for electrical engineers with a desire to understand different transformer testing procedures. Upon successful completion engineers will be able to understand different transformer testing procedures and specific procedures that need to be completed before the transformer is put into the service.
Learning Objectives

This PE continuing education course is intended to provide you with the following specific knowledge and skills:

  • Learning about transformer routine tests including IR, AC or DC hi-pot, Insulation PF, TTR, Polarity and Excitation current tests
  • Understanding the online transformer monitoring process
  • Learning about online monitoring of bushings and lighting arresters
