Objectives
The emphasis is put on the study of transformers and electrical motors, namely its classification, construction details, working principles, monitoring and working characteristics in steady regime. It is also intended that students acquire skills in testing, general rules of selection, installation, operation and maintenance, in its usage as autonomous elements as well as elements belonging to complex systems.

Program

2. Transformers
3. Asynchronous machines
4 Synchronous machines
5. Direct current machines
6. Protections, breakdowns and electric motors maintenance

Evaluation Methodology
Final grade:
NF = 0,5 x CT + 0,5 x CP

Theoretical component:
CT = TE or EF

TE - 4 tests
EF - final exam

Practical component :
CP - practical application project
