The group exhibition classes are conducted by: introductory activities, lecture, theory exposition, general examples and problems arising from the theory exposed. Internet consultation pages of accredited manufacturers related to different subject matters, consultation of related UNE standards.

Practice classes in groups. In the laboratory of electrical machines different types of machines are tested. The data obtained are analyzed and a report of the activity must be submitted through the Virtual Teaching Platform.

Students with special educational needs should contact the Student Attention Service (Servicio de Atención y Ayudas al Estudiante) in order to receive the appropriate academic support

The contribution to the paragraph of attendance and participation to the final qualification will be 15% (fifteen percent), random assistance controls will be made; participation in discussions, exercises, search and review of information relating to the matter will be considered.

The evaluation of the theoretical knowledge of the subject will be done through a written examination with content in theory and problems, to be held in the official call. The matter of this tests will be considered surpassed when equal to or greater than 5 over  10 points is reached. Theory and problems both must be pass. The qualification of theory assumes 70% (seventy percent) of the global. The theory part will consist of the response to several questions from the course contents, both the minimum content (basic bibliography) as additional content (specific bibliography for each subject) will be assessed, it is essential to obtain a minimum of 50% the score assigned to the theoretical part to pass. The part of problems solving is proposed among two and four problems on the contents of the subject (transformers and induction motors), it is essential to obtain a minimum of 50% score assigned to the theoretical part to pass.

For the qualification of knowledge of laboratory practices is mandatory performing all scheduled practices. The student will attend practices and submit a memory of the work done; Submission of activities will be held in the Virtual Teaching Platform. The evaluation of the reports, the resolution of practical cases, control schemes involving machines and simulations will be up to 15% (fifteen percent) of the note. Students who do not attend, do not submit reports or do not perform the various activities in full will not have the percentage indicated note. However a theoretical and practical examination of the practices will be conducted for those  students who prove their no attendance for justified reasons.
