DESCRIPTION

Transformers are major components of electrical power systems. This course combines theoretical and practical aspects of transformer design, operation, maintenance and troubleshooting. The course emphasizes the importance of the magnetic properties of the core design on the transformer’s operational performance and electrical properties. It addresses economic trade-offs of transformers in real-world applications.

 

HOW YOU CAN BENEFIT FROM THIS TRAINING

To provide a comprehensive understanding of principles, selection, testing and commissioning, protection, maintenance and troubleshooting of distribution, and power transformers.

 

WHO SHOULD ATTEND THIS TRAINING?

Electrical engineering professionals who need to update their knowledge, distribution system planners, maintenance managers, and power system consultants. The participants should have a basic understanding of power system operations, but do not necessarily have to be experts. Also, the engineers who are starting their career in the field of power in utilities, industrial or commercial plants and institutional complexes will benefit from this course.
