Instalações Elétricas Industriais

Teaching Methodologies

In the teaching/learning process, expository classes are used to present concepts, interactive classes where students actively interact in
class; examples of practical calculations using data compatible with real situations; group work and debates.

Learning Results

A – Understand the steps necessary to prepare an electrical installation project;
B – Understand the aspects that influence the safety and functioning of an electrical installation;
C – Understand and know how to apply technical criteria to the safe and efficient sizing of conductors and protective devices in an electrical
installation;
D – Understand and know how to implement a system to protect people against indirect or direct contact.
E – Dimension electrical installations taking into account technical, safety, economic and environmental aspects.
