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 know to identify the diverse phenomena (reactive, disequilibriums, harmonic), that can find in an electrical installation, that diminish his efficiency. AJ1

BC11
BC15
The student will know to quantify the importance of the ineficiencias of the system and proceed to pose the best solution for the same, so that the system was from the electrical point of view more efficient, all this attending to the norms and reglamentación valid. AJ1

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 B3 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 30% 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. 		30
Objective test A1 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 B15 The practical are compulsory, and is necessary to have them realised to be able to surpass the asignatura.

The practices represent 30% 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. 		30
 
Assessment comments

All the activities that contribute to the final note of the student, will be qualified on 10.0 points.
