Teaching language

Portuguese

Objectives

· To give the students a general survey on the electrical sector in Portugal.
· To present some equipment used in medium voltage facilities and, mainly, in low voltage installations considering the technological and functional characteristics. · To present the students the method of dimensioning electrical cables and their protections.
· To inform the students about the requirements of electrical projects concerning residential buildings.

Program

· Electrical Installations: some fundamental concepts.
· The electrical sector in Portugal: The topology of the networks (Generation, Transport and Distribution); Exploitation of the distribution networks in MV and LV; Electrical Legislation; The energy market
· Electromagnetic contactors. Electrical schemes.
· Underground cables. Tables of acceptable maximum currents.
· Evaluation of short circuit currents.
· Dimensioning of electrical cables and their protections. Circuit breakers and fuses.
· Relays: Types and characteristics.
· Overvoltages protection.
· People's security in electrical installations. Earth electrodes.
· Switchgear installations for medium voltage: Constitution and main types.
· Brief references about the execution of electrical projects concerning low voltage installations (residential buildings).

Teaching methods and learning activities

· Theoretical classes: Use of transparencies. These are available, as study material, to the students. The exhibition is illustrated with the visualization of the equipments, whenever such it is viable.
· Practical classes: Resolution of problems belonging to a list previously distributed the students.
· Visits to a medium voltage switchgear installation and to a factory of electrical cables manufacturing.

Evaluation Type

Not to attend classes more then the allowed maximum number of lacks.

Calculation formula of final grade

CLASS_FINAL(NF) = 0,875 x CLASS_Test(NE) + 0,075 x CLASS_FirstWork + 0,050 x CLASS_SecondWork.

Examinations or Special Assignments

First Work: A problem to be solved about Dimensioning of electrical cables.
Second Work: A practical one.

Special assessment (TE, DA, ...)

Is applied the formula: NF = NE.

Classification improvement

CLASS_FINAL(NF) = 0,875 x CLASS_Test(NE) + 0,075 x CLASS_FirstWork + 0,050 x CLASS_SecondWork.
