Objectives

Learning outcomes of the curricular unit:

At the end of the UC attendance, students should be able to:

1. Transmit knowledge and develop potentialities and capacities in the field of High Voltage Systems;
2. Prepare students for the correct use of High Voltage Systems and to carry out studies and tests in High Voltage Laboratories;
3. Design and develop projects to coordinate insulation in Power Systems;
4. Inform students about the importance of numerical simulation and laboratory tests.
5. promote critical thinking and skills at the individual work level for autonomous problem solving

Learning outcomes and competences

1. To transmit knowledge and develop students’ skills in the domain of High-Voltage Systems (CDIO Syllabus 1.3); 2. To prepare students to correctly use High-Voltage Systems and carry out studies and tests at High-Voltage Laboratories (CDIO Syllabus 2.1, 2.2, 2.3, 3.1, 4.1); 3. To develop projects of insulation coordination on SEE (CDIO Syllabus 3.3; 4.2; 4.5); 4. To inform students about the importance of numerical simulation and laboratory tests (CDIO Syllabus 3.3, 4.2 and 4.5).

Program

The main themes of the Curricular Unit of "High Voltage Techniques" are:

1. High voltage systems and their characteristics; atmospheric discharges and their consequences;
2. Overvoltages resulting from mains operation; possible biological effects from the electric and magnetic fields of High Voltage Systems;
3. Overvoltages of atmospheric origin and overvoltages of internal origin. Protection systems;
4. Experimental study of the overvoltages through field tests and laboratory tests.
5. Surge propagation: reference to the use of rapid transient simulation programs.
6. Properties and dielectric behaviour of insulators. Dielectric rupture and its mechanisms.
7. Protection of equipment against the effects of surges.
8. Earth systems.
9. 9. Coordination of insulation

Teaching methods and learning activities

Theoretical classes will be based on the presentation of the themes of the course unit. Students will be asked to participate in class. Theoretical-practical classes will be based on problem solving. Exercises will be beforehand provided. Students will also be asked to participate in class.  Students will participate in laboratory activities and they will be asked to write a critical report.

Eligibility for exams

According to General Evaluation Rules of FEUP, students are admitted to exams, if they write their reports and do not miss more theoretical-practical classes than allowed by the rules (25% of the classes). A visit to LAT, a High Voltage Laboratory of industrial dimension will take place, which is important in students’ training. Students will also be asked to write a critical report about it.

Calculation formula of final grade

Final Grade will be based on the average grade of the continuous assessment (50%) and the final exam (50%). Students have to reach a minimum grade of 40% in each of the components. 

Examinations or Special Assignments

Students have to do  mandatory assignments (monography and laboratory). Students may have to do extra assignments which can improve their marks.

Internship work/project

Not provided.

Special assessment (TE, DA, ...)

According to General Evaluation Rules of FEUP. Continuous assessment component is mandatory to be admitted to exams.

Classification improvement

A final exam as above mentioned. However, it may be an oral exam.

Observations

Any other situations not mentioned here will follow General Evaluation Rules of FEUP and, if necessary, this course director can be contacted.
