About this course

This course provides a foundation for electrical engineering principles and applications within the power sector.

Topics:

1) Electromagnetism and magnetic circuits

2) AC circuit analysis (Single-phase and three-phase)

3) DC machines (Motors and Generators)

4) Transformers

5) Induction machines

6) Synchronous machines

7) Special electrical machines (Single-phase machines)

Learning outcome

Electricity is one of the most important and cleanest energy carriers. The course focuses on topics such as converting mechanical energy into electricity through electrical generators, transmitting electricity over long distances using transformers, and utilizing electric power at the consumer level through electric motors and other appliances.

The course begins with lectures on the principles of electromagnetic induction and the Lorentz force, which govern the conversion of mechanical energy into electrical energy. After completing this section, students will be able to solve problems in electromagnetism and magnetic circuits.

The second section focuses on the principles and differences between direct current (DC), single-phase alternating current (AC), and three-phase AC systems. Students will also understand the concepts of efficiency, active, reactive, and apparent power and their critical roles in power systems. By the end of this section, students should be proficient in solving problems in DC, single-phase AC, and three-phase AC systems.

In the following sections, students will learn how to develop models for various electrical machines and solve problems in practical applications. The course emphasizes modelling and problem-solving of DC machines, transformers, induction, and synchronous machines.

Finally, in the laboratory exercises, students will familiarize themselves with operating and taking measurements with DC machines, transformers, induction and synchronous machines.

By the end of the course, students should have a comprehensive theoretical and practical understanding of basic electrical engineering principles and applications. They should be able to apply the learned knowledge to solve problems in practical applications.

  • Learning activities

    LECTURES: Teaching through lectures in the autumn parallel.

    CALCULATION EXERCISES: Calculation exercises will be given throughout the course.

    LABORATORY EXERCISES: Five laboratory exercises in the January block on essential electrical machines and principles.

  • Teaching support
    Canvas. Tutoring by teaching assistants. Meetings with teacher by appointment.
  • Prerequisites

    MATH111, MATH112, MATH113, FYS101, FYS102, FYS103,

    It is advantageous to have some knowledge of electrical circuits as covered in FYS235 Electronics

  • Recommended prerequisites
    FYS235, FYS236
  • Assessment method

    Written exam. 3.5 hours. A-F.

    The exam will take place at the end of January for students who have completed the laboratory part of the course in the January block.



    One written test Grading: Letter grades Permitted aids: B1 Calculator handed out, no other aids
  • Examiner scheme
    The external and internal examiners jointly prepare the exam questions and the correction manual. The external examiner reviews the internal examiner's examination results by correcting a random sample of candidate's exams as a calibration according to the Department's guidelines for examination markings.
  • Mandatory activity

    There will be two compulsory assignment submissions in the autumn parallel for being allowed to attend labs in the January block. The two compulsory assignments must be approved to participate in the course's laboratory part.

    You have to participate in a safety demonstration and must, in writing, accept the safety instructions for the laboratory part before you can partake in the laboratory part. All laboratory exercises must be conducted and must, including reports, be approved before you can take the final exam.

  • Teaching hours

    Autumn parallel: 52 hours, 2 hours twice a week. Exercises: 4 hours per week.

    January block: 5 laboratory assignments, duration 4 - 7 hours each.

  • Preferential right

    Ranking:

    1. students who have the course as mandatory in their study plan

    2. students on the following study programmes: B-EMF, M-MF, M-MPP, M-IØ, M-RB, M-LUR

    3. students with most ECTS credits

    It there are not enough slots in for the students in group one, the students will be ranked by their ECTS credits.

    Students taking the course for the first time have laboratory priority.

  • Reduction of credits
