Learning Outcomes

  1. describe electrical blueprints,
  2. analyze current transformers,
  3. analyze voltage transformers,
  4. analyze substation technical requirements,
  5. choose substation elements (busbar, switching devices, transformers, cables, grounding),
  6. apply knowledge about substation system design.

Forms of Teaching

Lectures

Lectures will be held two hours a week with the use of PowerPoint presentations and overhead projectors.

Seminars

During semester, students will create one seminar.
