EMPE2100 Electro technique, Measuring Technique and Statistics Course description

Together with the other natural science subjects, the course in statistics provides a foundation for the engineering subjects. This course provides students with an understanding of concepts in statistics and probability theory, problems and solution methods with the focus on applications in their own field and in the engineering field in general.

Measuring technique covers the basic principles of measurement theory, measurement of indoor environmental input parameters and measurements in ventilation systems. In connection with all types of measurements, the students must be able to assess measurement uncertainty and draw up an uncertainty budget.

In electrical engineeering, the students will learn the theoretical basis for calculating current, voltage and output in electrical circuits, gain an understanding of the structure of electrotechnical systems and of electrotechnical drawings and be introduced to acts and regulations. The course will give the students insight into electrical systems relating to indoor climate and optimum energy utilisation.

No requirements over and above the admission requirements.

After completing the course, the student is expected to have achieved the following learning outcomes defined in terms of knowledge, skills and general competence:

Knowledge

General competence

The student is capable of:

• using statistical ways of thinking to solve problems in engineering and communicating them orally and in writing
• solving problems in engineering by use of probability calculations, statistical experimental design, data collection and analysis
• assessing the uncertainty of different measurements
• performing indoor climate measurements and measurements in ventilation systems enabling assessment of local and general indoor climate conditions and the supplied airflow in a room
• calculating simple electrical circuits, explaining the principles of power systems and power components in Norway
• linking the engineering and operation of electrical systems to the indoor climate and optimum energy consumption, calculating and measuring energy consumption.

Lectures, exercises, laboratory exercises and excursions. In the exercise sessions, the students work on assignments, both individually and in groups, under the supervision of a lecturer and/or student assistant.

The following coursework is compulsory and must be approved before the student can sit the exam:

• 3 individual assignments in the form of calculation assignments, one for each of the subjects electrical engineering measuring technique and statistics
• 4 lab assignments in groups. The assignments cover electro technique and measuring technique.

Individual written exam, 3 hours

The exam result can be appealed.

A resit or rescheduled exam may take the form of an oral exam.

If oral exams are used for resit and rescheduled exams, the result cannot be appealed.

Aids enclosed with the exam question paper. A handheld calculator that cannot be used for wireless communication or to perform symbolic calculations. If the calculator’s internal memory can store data, the memory must be deleted before the exam. Random checks may be carried out.

Grade scale A-F.

One internal examiner. External examiners are used regularly.
