Working Principles of Transformers
APRIL 28, 2021 | 1:00 PM EST

An electrical power transformer is a static device which transforms electrical energy from one circuit to another without any direct electrical connection and with the help of mutual induction between two windings. It transforms power from one circuit to another without changing its frequency but may be in different voltage level.

This webinar provides a simple definition of transformers, as we will go through this session we will understand more clearly and deeply what is a transformer? How does it operate? What tests are performed on a transformer and what value do the tests offer? Topics will include:

  • Magnetism & Electromagnetism
  • Electromagnetic Induction
  • What is a Transformer?
  • How does a Transformer Work?
  • Power Transfer
  • Transformer Configuration
  • Transformer Ratings
  • Tests Performed for reliability assessments
