Non-sinusoidal waves. Three-phase system. Transformer principles and equivalent circuit. Electromechanical energy conversion. Transients in RLC circuits. Laboratory practice: impedance, admittance and electric power in alternating current circuits. Frequency changing in alternating networks. Three-phase symmetric networks. Three-phase unsymmetrical networks. Single-phase transformer.

Knowledge and skills acquired

Acquisition of knowledge of electric alternating circuits and transients phenomena required for the study of professional courses in electrical engineering.

Teaching methods

Lectures (3 hours per week), auditory exercises (2 hours per week) and laboratory exercises (1 hour per week). Power Point presentations are used in lectures. Students actively participate in auditory and laboratory exercises and are continuously tested.

Student requirements

Defined by the Student evaluation criteria of the Faculty of Electrical Engineering, Computer Science and Information Technology Osijek and paragraph 1.9

Monitoring of students

Defined by the Student evaluation criteria of the Faculty of Electrical Engineering, Computer Science and Information Technology Osijek and paragraph 1.9

Student assessment

Two revision exams during the semester and an oral exam for students who meet the requirements defined by the Student evalution criteria (points earned in revision exams and grade awarded in design exercises). Other students must take the written and oral exam.

Examination methods

Students' evaluation during the course and oral examination for students that satisfy by scoring, written and oral examination for other students.

Course assessment

Conducting university questionnaires on teachers (student-teacher relationship, transparency of assessment criteria, motivation for teaching, teaching clarity, etc.). Conducting Faculty surveys on courses (upon passing the exam, student self-assessment of the adopted learning outcomes and student workload in relation to the number of ECTS credits allocated to activities and courses as a whole).

Overview of course assesment

Learning outcomes
Upon successful completion of the course, students will be able to:

1. compare the mean, mean electrolytic and effective values of time-varying currents and voltages

2. explain the mathematical and graphical time dependence of voltage and current for transient phenomena in the coupling and discharge of the L and C elements connected to rectangular input voltage

3. choose the correct mode of representation in the phase-like impedance and circuit admitance with elements R, L and C connected to the alternating sinusoidal voltage

4. compare the terms for the current and voltage resonant frequency of the R-L-C circuit connected to the alternating sinusoidal voltage

5. derive expressions for apparent, active and reactive power in sinusoidal networks

6. derive expressions for phase and line voltages, make the three-phase asymmetric star-connected model and draw an appropriate scheme of the connection

7. derive expressions for phase and line currents, make the three-phase asymmetric delta-connected model and draw an appropriate scheme of the connection

8. describe the compound scheme and write the expression for the degree of a real transformer action loaded with work resistance
