MODULE DETAILS

MODULE 5: Power Transformers

 

Nominal duration: 2 weeks (16 hours total time commitment)

 

This time commitment includes the preparation reading, attendance at each webinar (1 hour plus 15-30 minutes for discussion), and the time necessary to complete the assignments and further study.

 

 

MODULE PURPOSE

 

 

 

The installation of high voltage distribution and transmission equipment has increased significantly over the years due to the ongoing global demand for power. As a result, the need to ensure the reliability of operation of power systems is paramount. Power transformers are among the most important and most expensive components of power systems, and their failure can impose extraordinarily high costs on plants, factories and utilities of all descriptions. It is critical that all personnel operating and working with such equipment have a sound knowledge of their operational requirements and maintenance. This module covers both the theory and operation of power transformers.
