Eletrotecnia e Medidas II

Theoretical classes: expository sessions with interaction between teacher and students.
Practical classes: problem-solving sessions and carrying out laboratory work that allow the practical application of learning, particularly in
the context of measurements and instrumentation.

The objective of the Electrical Circuits Theory and Measurements II curricular unit is to transmit to students the principles and notions of
Circuit Analysis concepts, in relation to single-phase and three-phase alternating current circuits and corresponding measurements.
The expository method together with the resolution of theoretical-practical problems allows the student to know and understand the
operating principles of electrical circuits and measurement systems. Laboratory classes practically complement the knowledge and skills
mentioned above

– Parallel RLC circuits. Power factor correction.
– Three-phase systems. Relationship between simple tension and compound tension. Balanced systems. Relationship between line current
and phase current. Power in three-phase systems.
– Transient phenomena in electrical circuits: RL and RC circuits. Analysis of RL and RC circuits with continuous inputs using Laplace
transform. Energy stored in the electric field or magnetic field. Analysis of RL and RC circuits with sinusoidal inputs using Laplace transform.
– Measuring bridges.
– General characteristics and operation of the main Measurement Transducers.
– Introduction to Signal Acquisition, Packaging and Conversion Systems.
– Interferences in measurement systems: causes and solutions.
– Virtual Instrumentation – Programming principles in LabVIEW
