Entry requirements

In order to meet the general entry requirements for first cycle studies you must have successfully completed upper secondary education and documented skills in English language and Circuit Theory I (ET074G), Circuit Theory 2 (5EL180), Algebra for Engineer (MA117G) and Calculus for Engineers (MA118G) (These courses are given by MiUn and UmU) or equivalent knowledge through practical work within electrical power engineering.

The selection is based on 1-165 credits.

Course Aim

The course consist of two different parts; Power distribution and power quality (EMC)

After finishing the course you as a student should have:

Knowledge and understanding:
-about different equipment used in low- and medium voltage network
-about basic principle of different protections units used in low- and medium voltage network
-about different fundamental  concepts of power quality
-about how different disturbances spread in our networks
-about standards and regulations that apply to the area
-about current research in the field of power quality

Skills and ability:
-how to perform short circuit calculations in various electrical systems
-how to calculate the voltage drop in the electrical installations
-how we design electrical systems
-to identify the various sources that generate power quality related problems
-to deal with strategies to reduce power quality related problems

Ability of assessment and attitude:
-if an electrical installation meets the basic technical requirements we normally impose on these
-to make judgments regarding the protection and electrical safety


The main focus of the course can be described as the low-voltage and medium-voltage part.

In the course we will go through:
-Components (transformer stations , substations, cables, overhead lines , circuit breakers, switchgear , breakers, capacitor, insulators, etc.).
-Protection (fuses, protective relays, Arc Monitors , RCDs , etc.)
-Earth and shielding systems (ground, earth- neutral reactors , zero resistance , potential equalization , capacitance , etc.).
-Short circuit calculations , principles of over-current protection in distribution networks
-Voltage regulation and voltage drop calculations in low and medium voltage networks
-The interleaving of loads, load capacity
-EMC and Power Quality
-Standards of EMC and power quality , EMC Directive
-Dips , voltage swells and interruptions
-Harmonics , unbalance and flicker
-Transients , lightning , power surges

This course is aimed at those starting with a smaller grid company or industry.

Teaching at a distance and labs done at campus Skellefteå. Some of the labs is in cooperation with energy companies and aims to provide insight into the link between theory and practice.
