Assessment methods
Achievements will be assessed by the means of a final exam. This is based on an analytical assessment of the "expected learning outcomes" described above.
In order to properly assess such achievement the examination consists of a written/oral session with 3 questions on topics of the course, to ascertain the knowledge of the student and the ability to apply such knowledge in simple practical problems.The first question is a written theme that must be done in 1 hour without the help of notes or books. The other two questions asked by the teacher are instead discussed orally. Each question is given a score from 0 to 11. In order to pass the exam successfully, the score received in each single question must be higher than 5. The final grade is given by the sum of the scores obtained in the three questions. If the final grade is greater than 31, the LODE is awarded.
To obtain a passing grade, students are required to at least demonstrate a knowledge of the key concepts of the subject, particularly regarding protections against indirect and direct contacts in electic distribution networks, some ability for critical application and an acceptable use of technical Language.
Higher grades will be awarded to students who demonstrate an organic understanding of the subject, a high ability for critical application, and a clear and concise presentation of the contents.
A failing grade will be awarded if the student shows knowledge gaps in key-concepts of the subject, in particular on energy storage, supercondutvitiy and fotovoltaic systems, as well as inappropriate use of language, and/or logic failures in the analysis of the subject.
