Course Catalogue.

After Participating in this course, you will be able to:

• Understand electromagnetism as it relates to transformers
• Identify power and instrument transformers
• Understand three-phase connection variations
• Understand the various types of transformer protections
• Identify some of the mechanical and cooling features of transformers

Description:
This course is designed around an understanding of transformers from a protection and control aspect. It starts with a fundamental understanding of the principals of electromagnetism as it applies to voltage and current transformation and examines core types and three-phase transformer construction. Instrument transformers are reviewed including the phenomena of saturation effects on relaying.

Power transformer losses are discussed. Three-phase transformer configurations are examined as well as Y, Delta and ZigZag combinations along with the current and voltage vector relations. The mechanical aspects are also briefly examined, including cooling and oil analysis.

Course Outline:

• Electromagnetism
• Potential and current transformers
