Course information

Content and learning outcomes

Course contents *

  • consequences of errors in components of electric power systems
  • electric dangers for people and property
  • protection against excess currents at low voltage
  • protection against current breakdown in low voltage plants
  • measurement transformers and other sensors
  • different generations of protection relays
  • system grounding and grounding faults in distribution networks at medium voltage
  • protection principles in distribution networks including current and/or time
  • protection of transmission lines: differences
  • differential protectors and distance protectors
  • transformer faults and protective system
  • dynamos and engines
  • new challenges: sustainable development, the dynamos of new blows, DC-circuits, higher speed, new algorithms, more communication.

Intended learning outcomes *

After passing the course, the student should be able to

  • present basic concepts and solve standard problems from the major part of the course content.

To obtain higher grades, the student shall be able to

  • with progression in both completeness and width, make clear and justified assessments and calculations from all parts of the course content including problems that require synthesis from different parts of the course content and qualifying courses.

Literature and preparations

Specific prerequisites *

Completed courses equivalent EI2436 Power Grid Technology and Substation Design and EG2100 Power System Analysis.

Active participation in a course offering where the final examination is not yet reported in LADOK is considered equivalent to completion of the course. This applies only to students who are first-time registered for the prerequisite course offering or have both that and the applied-for course offering in their individual study plan.

Recommended prerequisites

Also recommended is the course EH2741 Communication and Control in Electric Power Systems.

The course is not suitable for students who have not already studied at master's level in electric power engineering.

Examination and completion

If the course is discontinued, students may request to be examined during the following two academic years.

Grading scale *

A, B, C, D, E, FX, F

Examination *

  • PRO1 - Project Work, 3.0 credits, Grading scale: P, F
  • TEN1 - Written Examination, 3.0 credits, Grading scale: A, B, C, D, E, FX, F

Based on recommendation from KTH’s coordinator for disabilities, the examiner will decide how to adapt an examination for students with documented disability.

The examiner may apply another examination format when re-examining individual students.

Opportunity to complete the requirements via supplementary examination

Ethical approach *

  • All members of a group are responsible for the group's work.
  • In any assessment, every student shall honestly disclose any help received and sources used.
  • In an oral assessment, every student shall be able to present and answer questions about the entire assignment and solution.
