Subject aims expressed by acquired skills and competences

Students will learn to use electrical measuring instruments, measure basic electrical quantities and passive elements. An integral part of the student's competence is also the knowledge of quantification of measurement uncertainty.

Teaching methods

Lectures
Individual consultations
Experimental work in labs
Teaching by an expert (lecture or tutorial)

Summary

Students will learn to use all types of measuring instruments from analog to digital to virtual instrumentation. Students will be able to measure basic electrical quantities and passive elements by a number of methods. Special chapters are dedicated to expressing the uncertainty of the measurement result. The subject contains 10 laboratory measurements. Theoretical support for measurements is discussed in lectures.

Lectures: 1.Accuracy and error of measurement. Errors of analog and digital instruments, errors of direct as well as indirect measurements, random errors, total measurement error. Measurement uncertainty. No harmonic waveforms of electrical quantities. Representation of periodical waveforms using Fourier transformation; form, crest and distortion factors. 2.Measuring converters (MTI, MTU). 3.Analog measuring instruments. 4.Digital measuring instruments. 5.Analog oscilloscopes. 6.Digital oscilloscopes and recorders. 7.Frequency analyzers. 8.Virtual measuring instruments, GPIB, RS 232, USB, Ethernet, VXI/ PXI measurement systems, development programming environments. 9.Methods for measuring active electrical quantities (voltage, current, power, frequency, period, time intervals). 10.Methods for measuring passive electrical quantities (resistor, inductance, capacitance, dissipation factor, quality factor, impedance). 11.Magnetic measurements. Measuring of ferromagnetic characteristics, display of hysteresis loops. 12. Disturbing effects and their limitation, EMC. Laboratories: -Initial theoretical training, protocol requirements, safety in the laboratory. - 1. Measuring of voltage and current. - 2. Measuring of passive components. - 3. Impact of frequency and waveform shape on measuring instrument's indication. - 4. Analog oscilloscopes. - 5. Measuring of single-phase power. - 6. Measuring of powers across unbalanced three-phase load. - 7. Measuring of frequency, period and phase shift. - 8. Measurement of characteristics of ferromagnetic materials. - 9. Virtual instrumentation – virtual measuring instruments - 10. Digital oscilloscope and its control using GPIB bus. - Practical test measurement. Projects: 10 measurement reports - theme depends on laboratory exercises. Tests: 10 test questions - 1 in each exercise, according to the measured task. The questions are tied to the measurement of the task.
