List of learning outcomes:
A) Knowledge or content
Con08: Knowledge and use of the principles of the theory of electrical circuits and machines.
Con10: Knowledge of the fundamentals of automation and control methods.
B) Skills or abilities
H/D01: Teamwork.
H/D04: Critical reasoning and ethical commitment.
H/D05: Ability to apply knowledge in practice.

Comp08: Ability to solve problems with initiative, decision-making, creativity, critical thinking, and to communicate and transmit knowledge, skills, and abilities in the field of Industrial Engineering.
Comp09: Ability to handle mandatory specifications, regulations and standards.
Comp14: Knowledge, understanding and ability to apply the legislation necessary for the practice of the profession of Industrial Technical Engineer.
Part I. Expository classes and seminars:
In theoretical and seminar classes, continuous assessment will be carried out, and attendance is not mandatory.
The lectures will combine theoretical content presentations with practical exercises that illustrate the theoretical content. During the in-person seminars, students will complete practical exercises and solve problems that deepen the knowledge acquired in the lectures. Tests will also be given to assess the student's understanding of the content covered in the lectures. Student participation will be sought up and encouraged, both in lectures and seminars. In addition, specific software will be used for electrical installation design and cross-section calculations.
A technical visit is planned, if possible, in collaboration with other first-year subjects, as part of the visits scheduled for the second semester of the Chemical Engineering Degree.
The planned schedule of the main activities is summarized below:
- Week 4: resolution and presentation in seminar class of a single-phase alternating current problem.
- Week 8: resolution and presentation in seminar class of a three-phase alternating current problem.
- Week 11: resolution and presentation in seminar class of a problem on electric motors.
- Weeks 8-11: Technical visit (final date will depend on the availability of the company visited).
- Week 16: Completion and submission of a final test with theoretical and practical content in the seminar class.
Part II. Workshop practices:
Attendance at all practical sessions of the workshop is mandatory.
In workshops on basic maneuvering and automation of electrical machines, students will work in teams of three to four people, assembling various circuits that integrate various power and control elements. At the end of the experimental practices, each team will submit a report/notebook on the proposed activities.
Group tutoring:
A team project will be completed, designing an industrial electrical installation using the specific software presented during the seminar classes. This project will be submitted through the Learning Management System. During the group tutoring session, an oral presentation of this project will be given. The group tutoring activities (submission and presentation of the project) will take place approximately in weeks 14-15.
Individual tutoring sessions requested by students to resolve any questions will be conducted in person or, where appropriate, remotely via MS Teams.
A Learning Management System (Moodle) will be used for distributing teaching materials, administering tests, sending notifications, and submitting activities. The use of spreadsheets and specific software for electrical installation design will be encouraged to solve some of the proposed problems.
The evaluation will be the result of the sum of the following partial assessments:
a. Exam: 50% (mandatory).
b. Continuous evaluation: 20% (including technical visit).
c. Workshop practices: 20% (mandatory).
d. Group tutoring: 10%.
Attendance at all workshop sessions is mandatory to pass the course. Attendance at workshop sessions is mandatory, as established by the regulations of the University of Santiago de Compostela, and absences must be justified in accordance with the regulations.
Attendance at the lectures and seminars, as well as the technical visit and group tutorials, is recommended to ensure you are fully aware of the content and obtain the corresponding evaluation.
Continuous assessment includes the seminar evaluation tests, attendance to the technical visit, and the professor's report.
To pass the course, students must obtain a minimum score of 40% of the maximum grade for the exam and workshop exercises, and a minimum overall grade of 5.0. The maximum grade a student would receive if they do not exceed the minimum score for the exam or workshop exercises would be 4.9, or fail. The course exam consists of two parts: theory (30% of the overall exam grade) and problems (70% of the overall exam grade). The theoretical part will assess the content acquired in the classroom, workshop exercises, and group tutorials.
Before the final exam, students will be given their marks for the continuous assessment, practicals, and group tutorials. Students who have completed the practicals but have not passed the minimum 40% mark may be re-evaluated before the second-chance exam.
The student who has not completed any of the mandatory activities will be considered NOT PRESENTED.
In cases of fraudulent completion of exercises or tests, the provisions of the " Normativa de avaliación do rendemento académico dos estudantes e de revisión de cualificacións" will apply.

SAFETY IN THE PRACTICE WORKSHOP:
Admission and continued participation in the practical workshop requires that students familiarize themselves with and comply with the regulations included in the "Basic Safety Training Protocol for Experimental Spaces" of the Higher Technical School of Engineering, available in the safety section of its website, which can be accessed as follows:
1. Access your intranet.
2. Go to Comisións/Seguridade e Saúde/Formación.
3. Click on “Protocolo de formación básica en materia de seguridade para espazos experimentais”
In addition, students will be provided with a practical guide, which will include the most relevant aspects related to safety and risk prevention associated with the use of electricity.
