Content

Lab electrical machines at industrial voltage levels.

The first session is an introductory lesson with mandatory safety briefing. Students who didn't follow a safety briefing are not allowed in the lab. Lab sessions on following topics

  • Transformers
  • DC motor and generator
  • Synchronous generator
  • Induction motor

 

Course material

Lab texts on Toledo

Format: more information

Laboratory session

Lab electrical machines at industrial voltage levels. Remark: Without safety briefing access to the lab is denied.

Each lab test is prepared. Students work in teams on the lab assignments and take responsibility. They choose measuring equipment, build circuits and carry out measurements, with an eye for safety and accuracy. They interpret their results and present their findings in a report.

Evaluation

Evaluation: Electrical Machines (B-KUL-T72249)

Type : Partial or continuous assessment with (final) exam during the examination period
Description of evaluation : Oral, Written, Report, Participation during contact hours, Skills test
Type of questions : Multiple choice, Open questions
Learning material : Course material, Calculator, Reference work

Explanation


1. Establishment of the final mark

The final mark of this course is calculated based on the published partial grades with the following weighting factors:

  • Partial grade for lectures: 60%
  • Partial grade for lab sessions: 40

The only exception to this rule is described in the complementary regulation of the Faculty of Engineering Technology to article 66 in the Regulations on Education and Examinations.

2. Establishment of the published partial grades

OLA lectures
The partial grade for the lectures is an integer out of 20. The exam is closed book. Use of a calculator is allowed. A student, however, can not succeed for the course if he/she hasn't acquired sufficient understanding, knowledge or skills. Mistakes against prior knowledge will result in a not-tolerable exam result.

OLA Practica
The partial grade for the lab sessions is an integer out of 20.

  • An individual test at the end of the sessions. Working efficiently is an evaluation criterion, so the time is limited.
  • Bonus/malus based on reports of online and/or on-campus sessions - as far as they took place.
  • Bonus/malus based on permanent evaluation during contact moments - as far as they took place 

We expect the students to behave as aspirant engineers. Deviant behaviour will be assessed. The quotation isn't an algebraic sum of the different sub quotations. To clarify but certainly not limitative: A student with excellent knowledge who lies, is a danger to our profession and will get a low quotation.  A student who attends motivated every class, but make errors against the fundaments of the electricity is also a danger in our profession and will also get a low quotation. In case of serious shortcomings or serious mistake against the lab regulation a student can be denied access to the Lab. The student does not get a grade for this sub course. The student has to redo this sub course and cannot pass the course until he has passed this sub course with success. This is exceptional and the student will be informed of this decision by email.

3. Absences

Unauthorized absence during the exam leads to NA as a partial grade for lectures.

Unauthorized absence during one or more lab sessions leads to NA as a partial grade for the lab sessions.

Remark: Without safety briefing access to the lab is denied.

For absences during the teaching weeks, please contact the education ombuds on the first day of your absence. If you missed one or more obligatory sessions, please contact your professor as soon as possible and certainly within a week. For absences within the exam period, please contact the exam ombuds on the first day of your absence.
