NorwegianRecommended prerequisites
The course assumes that students have knowledge equivalent ELE100 Electric Circuits, ENE233 Electrotechnical basis and ENE229 renewable energy in the power grid. In addition, students should have a solid foundation in arithmetic with complex numbers and vectors.
Course contents
Working with electricity is associated with danger and therefore require accuracy and system overview. The area is highly regulated by laws and regulations, and those who work with electricity must be able to follow safety procedures to prevent accidents. The course emphasizes basic knowledge of laws and regulations for safety. Each task is performed on the basis of evidence, rules and regulations. The purpose of this course is to enable the candidate to understand how skilled workers performs tasks in various live plants in small and large buildings.
The course describes and explains lightning pennies and their propagation in an electrical network by using traveling wave model and reflection diagram. Overvoltages and temporary overvoltages are also presented. High voltage components like cables, fuses, circuit breakers and surge arresters will be processed. The physical processes with regard to the impact mechanism in gases and solids will be discussed and explained.
Learning outcomes
On successful completion of the course, the student should be able to:
-
explain key concepts and components of low voltage systems
-
describe various techniques and equipment used in the installation, maintenance and repair of low voltage systems, and explain how this work affects the environment
-
know the regulations and standards
-
understand the operation and use of equipment for troubleshooting and measurement
-
know the uses of different types of switches and protective
-
explain penetration mechanisms in gases and solids
-
explain the function and structure of the following high voltage components: metalloksydavleder, switch, fuse and cable
-
process and lay cable
-
use relevant brand and coding systems for materials and equipment
-
select the right equipment and materials in relation to certain procedures and tasks and be able to check that tools and equipment are in safe working order before use
-
apply relevant computer tools associated with low voltage
-
perform electrical calculations, calculate the cross-section area and selecting the corresponding protection using available substrates such as tables, charts and computer programs, etc.
-
calculate lightning pennies on a high voltage net using traveling wave model
-
calculate voltages, electric field strength and potentials by hand bill
Examination requirements
Mandatory and assignments must be approved to take the exam.
Teaching methods
Lectures, demonstrations, laboratory exercises and exercises done by hand and with the use of computer programs.
Estimated work load for the average student is 27 hours per credit.
Evaluation
The study programme manager, in consultation with the student representative, decides the method of evaluation and whether the courses will have a midterm- or end of term evaluation, see also the Quality System, section 4.1. Information about evaluation method for the course will be posted on Canvas.
Assessment methods and criteria
Written individual exam, 4 hours. Graded assessment.
