General description Para conseguir que as instalacións eléctricas e os receptores que as constitúen, traballen dunha maneira correcta e que traballen dunha maneira eficiente desde un punto de vista eléctrico, hanse de primeiramente identificar e logo cuantificar dunha maneira correcta as ineficiencias que nos podemos atopar presentes en calquera sistema eléctrico, tales como os desfasamentos entre a tensión e a corrente, a falta de simetría e a falta de linealidad nos seus circuítos, unha vez establecidas estas ineficiencias, mostrásense os dispositivos que nos permiten corrixilas, de maneira que se logre unha mellora na eficiencia da instalación ou circuíto.

Learning aims
Learning outcomes Study programme competences
The student will identify the various phenomena (reactive, imbalances and harmonics) that can be found in an electrical system or installation, which reduce its efficiency, will know how to quantify their importance and proceed to propose the best solution for them, so that the system is as efficient as possible from the electrical point of view, in accordance with current standards and regulations.

Methodologies
Methodologies Description
Objective test Proof of evaluation where the student will have to show his degree of learning of an objective way.
Laboratory practice You practise them of laboratory are a fundamental activity for the learning of this matter. They consist in practical suppositions where the student will have to show the theoretical knowledges purchased
Supervised projects They develop tasks, that allow to settle the theoretical and practical knowledges, that can go from formulating problems and brief works the simple until others with some complexity.
Guest lecture / keynote speech Face-to-face activity in the classroom, where will establish the fundamental concepts of the matter. It will realise by means of an oral exhibition, complemented with audiovisual and multimedia means, is whose end transmit the knowledges and facilitate the learning.

Assessment
Methodologies Competencies Description Qualification
Supervised projects B15 C3 Will be able to realise to varied cape works tutelados along the course, being his compulsory delivery and that treated on problems or practical suppositions related with the matter.

The works tutelados, are 50% of the final note of the matter, that will be added to the note obtained in the objective proof, whenever this was described with at least 3.0 points on 10.0 points.
50
Objective test B1 B6 B7 In the dates fixed officially by the centre, realised this final proof.

The proof can alternate ask type problem or theoretical questions, and represents 40% of the final note of the matter.
40
Laboratory practice B6 B11 The practical are compulsory, and is necessary to have them realised to be able to surpass the asignatura.

The practices represent 10% of the final note of the matter, and added to the note obtained in the theoretical proof whenever this was upper to 3.0 points on 10.0 points.

Assessment comments
All activities that contribute to the student's final grade will be qualified out of 10.0 points.

Second opportunity: the evaluation on this occasion will be the same as the first opportunity, keeping the weights of the activities.
Advanced call: in this call or 100% of the qualification will correspond to obtained in the Objective Test.

The students with recognition of part-time dedication and academic exemption from assistance must carry out all the mandatory activities at any two schedules established in advance.

A fraudulent performance of the tests or evaluation activities, once verified, will imply that the student will be qualified with "fail" (numerical grade 0) in the corresponding call of the academic year, both if the commission of the fault occurs at the first opportunity like a second For this, proceed to modify your qualification in the first opportunity certificate, if necessary

Other comments

Previous knowledge of analysis of direct current, alternating current and three-phase circuits, as well as symmetrical components, is required.

In another order of things, to help achieve a sustained immediate environment and meet the objective of action number 5: "Healthy and sustainable environmental and social teaching and research" of the "Green Campus Ferrol Action Plan":

            The delivery of documentary work carried out in this matter:

              • They will be requested in virtual format and/or computer support.

              • It will be done through Moodle, in digital format without the need to print them

              • If it is necessary to do them on paper:

                  - No plastics will be used

                 - Double-sided prints will be made.

                 - Recycled paper will be used.

                 - The printing of drafts will be avoided.

• A sustainable use of resources and the prevention of negative impacts on the natural environment must be made.

A gender perspective is incorporated into the teaching of this subject (non-sexist language will be used, bibliography of authors of both sexes will be used, intervention in class by male and female students will be encouraged...)
