General Competencies

The objectives of the course are to give the students the knowledge about low voltage power systems. Upon the completition of the course, students will be qualified to do following: 1.planning and design of low voltage power systems; 2. project management for low voltage power systems

Learning Outcomes

  1. identify basic components of medium and low voltage installations
  2. employ software solutions for modelling LV networks and calculation of protective device selectivity
  3. choose adequate equipment for specific implementations in LV network
  4. explain the role of individual components in LV distribution systems
  5. estimate usefulness of individual protective devices in LV networks
  6. synthesize theoretical knowledge of designing LV networks with software tools
