Measurement Techniques

Fundamental principles and strategies of measurements; Measuring accuracy and uncertainty (absolute and relative errors, measurement result, statistic analysis, measurement uncertainty); Metrology systems (quantities, units and realization, etalons, disemination, traceability, calibration, conformity assessment); Measurement of electrical quantities (voltage, current, power, resistance, capacitance, inductance, frequency, phase angle, power factor, frequency spectrum, …); Application of basic measuring instrumentation (ammeter, voltmeter, wattmeter, oscilosscope, etc.); Structure of measuring instruments and systems (structure and elements, static and dynamic characteristics, influence quantities, analog and digital conditioning and signal processing); Electronic measurement instruments (multi-meter, digital electronic osciloscop, universal counter, instrument with computer and wirtuak instrumentation) and suitable signal conditioning circuts  (shunts, voltage dividers, measurement transformers, etc.); Reduction of the  influence of disturbing signals and measurement bridges; Measurement of quantities, which define power quality (voltage sags and swings, apparent power, reactive power, etc.); Measurement of non-electrical quantities (temperature, humidity, preasure, force, lenght, noise, etc.).

The course introduce basic knowledge of metrology and measurements of technical quantities. Objectives of the course are:

a) To introduce the basic principles of measurement of most important quantities in engineering, properties of measurement signals;

b) To introduce the basic principles of digitalization of the measurement signals in the time and frequency domain;

c) To learn the approaches and methods of measurement of basic electric quantities and caracteristics of measurement transducers;

d) To study the meaning of statistic and analysis of measurement uncertainty;

e) To study the fundamentals of metrology and metrological systems, Si units, connections with other fields of science;

f) Introduction in the laboratory-instrumentation practices and to learn the security requirements and protection in measurements.

Lectures, laboratory tutorials, laboratory work in small groups, solving practical tasks (problems).
