Course content

Planning of electrical installations: Analysis of needs, calculation of power demands for heating and lighting. Structures for electical systems, topology and topography. Low voltage distribution systems (IT,TT,TN). Distribution and dimensioning of circuits. Safety precautions for electrical installations. Equipment and methods for protection: Overcurrent protection, earth fault protection, overvoltage protection. Discrimination. Earthing systems. Installation and equipment. Installation bus systems. Emergency and backup power supply. Software tools.

Learning outcome

After completing this course the candidate shall be able to give an account of:
- relevant low voltage supply systems in Norway, and their characteristics
- different structural system solutions, and their characteristics
- design and characteristics of various kinds of overcurrent protection, earth fault protection and overvoltage protection

After completing this course the candidate shall be able to:
- make basic lighting and heating calculations for buildings
- calculate fault currents and fault voltages
- calculate voltage drops
- use relevant regulations and standards for electrical low voltage systems
- dimension cross section area and overcurrent protection in electrical installations
- commission simple PLC and installation bus systems

The student will also have increased his/hers abilities to use instruments and equipment in the laboratory.

Learning methods and activities

Lectures, compulsory exercises and laboratory work. Compulsory project work. The final evaluation will be based on a written examination (counting 70%) and the project work (counting 30%) based on % fulfillment. Final grading will be from A to F. If there is a re-sit examination, the examination form may change from written to oral.

Compulsory assignments

  • Laboratory work with report
  • Exercises

Specific conditions

Exam registration requires that class registration is approved in the same semester. Compulsory activities from previous semester may be approved by the department.
