COURSE NO: E05-013
Introduction to Transformers
Course Highlights

This online engineering PDH course describes the basic concept, function, types, and the different components of electrical transformers.  


A transformer is an electrical equipment that transfers energy from one circuit to another by electromagnetic induction. They are often used to convert between high and low voltages (step-up or step down). Transformers and their components vary depending on the application and are available in several different configurations.  


This 5 PDH online course is applicable to electrical and mechanical engineers, maintenance personnel and other technical staff who are interested in gaining a better understanding of transformers.
Learning Objectives

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

  • Understanding the function of transformers and their physical characteristics
  • Familiarizing with the different components of transformers
  • Learning how to identify a transformer as step-up or step-down and state the current ratio of a transformer when given the turns ratio
  • Learning the mathematical relationship between the power in the primary and the power in the secondary of a transformer
  • Understanding the basics of the different types of transformers
