- Course Outline
Transformers are an indispensable part of electrical power systems. This course combines theoretical and practical considerations and aspects of operational principles of transformers, their types, selection, testing, maintenance and troubleshooting. The course emphasizes transformer's operational performance characteristics and electrical properties. The discussion is based on the latest Standards governing transformers and applications.
To provide a comprehensive understanding of principles of operation, types, selection, testing and commissioning, protection, maintenance and troubleshooting of electric power and distribution transformers.
Electrical professionals who need to refresh and expand their knowledge, distribution system planners, maintenance managers, and power system consultants. A basic understanding of electrical power system operations is needed, but participant do not necessarily have to be experts in the areas covered. In addition, professionals who are starting their career in the field of power in electrical utilities, industrial or commercial and institutional facilities will profit from this course.
