Description

Transformer station are among the most important and most expensive components of power systems, 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 practical workshop provides knowledge on both the theory and operation of Transformers. The course will develop and enhance an understanding of what is involved in the maintenance of these essential components of the power systems, through the tips and tricks learnt and developed by some of the World’s preeminent electrical engineers.

 

Course Objective

• An understanding of the fundamental theory and principles of the operation of transformer
• An insight into the identification and application of transformers’ types
• An understanding of the power transformers components and their construction
• Knowledge of power transformer protection
• Learn how to select, use and analyze relay protection usage in transformer system
• Improve knowledge how to properly maintain transformer
