Syllabus Information

1. General information

The main objective of the subject is to understand and be trained in the interpretation of the electro-magnetic phenomena underlying low voltage electrical installations in order to be able to evaluate and justify the choice of the elements that are part of these installations, having the necessary tools to carry out a low voltage electrical project in the agro-industrial field.

These approaches and objectives are aligned with the following Sustainable Development Goals (SDGs) of the United Nations Agenda 2030 () 2030 of the United Nations (https://www.un.org/sustainabledevelopment/es/), contributing to some extent to their achievement: Goal 7: Affordable and non-polluting energy, Goal 9: Industry, innovation and infrastructure.

2. Learning results

• Classify, analyze, calculate and design the use of direct current and alternating current electrical circuits in single-phase and polyphase systems, which cover the needs of agricultural and livestock farms and agro-food industries.

• Analyze, calculate and design energy needs, electrical power and its distribution in farms, agribusinesses, food industries and green areas, giving priority to their energy efficiency (in line with goals 7.3 and 9.4)

• Design, calculate and define the link installations and electrical circuits that make up the low voltage electrical installations in low voltage electrical installations in farms, agri-food industries and green areas.

• Identify, analyze and justify a lighting installation to meet the needs of farms, agribusinesses, food industries, green areas and sports facilities.

• Identify, interpret, calculate, design and justify the elements of maneuver, measurement, protection and safety in low voltage installations in farms, food industries and green areas.

• Justify a low voltage electrical installation project in farms, agribusinesses, agri-food industries and green areas.

5. Assessment system

The subject will be assessed by means of a global face-to-face test. Its content will be adapted to the syllabus of the subject (theoretical sessions, problems and laboratory) and its realization will take place once the teaching semester is over, according to the date scheduled in the EPS exam calendar for the official calls of the correspondingacademic year.

The final global test will consist of a face-to-face exam consisting of four blocks:

• Block 1: theoretical part, multiple-choice questions and short theoretical-practical questions. 40% of the final grade (minimum 3.5 out of 10).

• Block 2: practical part, problems on electrical applications and installations (part I). 40% of the final grade (minimum 4.0 out of 10).

• Block 3: practical part, problems on electrical applications and installations (part II). 10% of the final grade (minimum 4.0 out of 10).

• Block 4: practical part, dedicated to computerized practices. 10% of the final grade (minimum 5.0 out of 10).

In blocks 2 and 3, the students will be able to have as support a form/guide, of their own elaboration and with a maximum length of 2 DIN-A4 pages.

Blocks 3 and 4 may be passed during the semester (without prejudice to the student's right to take the final global test, notifying the responsible teacher with sufficient time in advance). For this purpose, the following complementary assessment activities are proposed:

• Block 3: Weekly problem/case deliveries.

• Block 4: Laboratory session reports. During the laboratory sessions, the students will be asked to carry out exercises with the different computer tools at . It will not be necessary to write reports or memoirs if you attend these classes, since the teacher will review the exercises on site. In case of non-attendance it will be necessary to solve individually the proposed exercises and write a report or memory of the session Assessment criteria

• Understanding of laws, theories and concepts

• Correct use of units in quantities

• Clarity in the presentation of results

• The correctness of the approach, the results and their interpretation

• Spelling mistakes

The grade of blocks 1 and 2 will not be kept for the first and second summons. The grade of blocks 3 and 4 may be saved (if the student wishes) for successive examinations, corresponding to academic years other than the one in which it was obtained..

Calculation of the final grade:

The final grade (CF) out of 10 points, will be obtained by applying the following equation:

CF = (0.40 × grade block 1) + (0.40 × grade block 2) + (0.10 × grade block 3) + (0.10 × grade block 4)

In order to pass (CF > 5.0) it is essential that: [grade block 1 > 3.5], [grade block 2 > 4.0], [grade block 3 > 4.0] and [grade block 4 5.0]

In the event that the above requirements are not met, the final grade will be obtained as follows: If CF > 4, the final grade will be: Fail (4.0)

If CF < 4, the final grade will be: Fail (CF)
