Teaching Methodologies
The curricular unit will be taught in a combination of exhibition methods, exercise resolution and conducted reflection. It may also include other methodologies, including study visits, participation in lectures or seminars, specifically or generally organized, which are considered appropriate to the learning objectives, included or not in the expected contact hours of the Curricular Unit. Group work and presentations may also be carried out to their pairs (not exclusively).
Learning Results
Be able to Identify primary energy sources and their usefulness in the production of electricity, with or without heat generation, as well as conversion processes between different forms of energy.
To understand the structure of electrical networks and the possibility of coexistence of AC and DC networks, identifying and enunciating principles of conversion, advantages and disadvantages, as well as possible impacts on electrical networks.
Identify and characterize loads of electrical grids, motors, and their drives.
To understand the principles of installation, sizing and protection of industrial electrical conduits, and their interconnection with protection schemes against direct and indirect contacts. Risks and procedures for intervention in electrical networks, without or with tension.
To know applicable energy tariffs, interpret their components, optimize energy costs and discuss cost reduction alternatives through consumption reduction.
