Subject description

Prerequisits:

  • Enrolment in the second academic year

Content (Syllabus outline):

  • Fundamental principles and methods of measurement;
  • Measurement of electrical quantities (voltage, current, power, resistance, capacitance, inductance, frequency, phase, power factor, ...), and estimation of basic three parameters of the periodic quantities (frequency, amplitude, and phase angle);
  • Analysis of errors in the acquisition of measurement signals with suitable signal conditioning (shunt, voltage divider, measurement transformer etc.);
  • Reduction of the influence of disturbing signals and measurement bridges;
  • Structure of measuring instruments and systems (structure and elements, static and dynamic characteristics, influence quantities, analog and digital conditioning and signal processing).
  • Measuring accuracy and uncertainty (absolute and relative errors, measurement result, true value, statistic analysis, measurement uncertainty), signal conditioning;
  • Metrology systems (quantities, units and realization, etalons, disemination, traceability, calibration, conformity assessment);
  • Measurement of non-electrical quantities (temperature, humidity, preasure, force, lenght, noise, ...).

Objectives and competences:

  • To get acquainted with the basic knowledge of measurements and principles and methods of measurement of the most important quantities in engineering and their parameters;
  • To understand the concept of evaluation of the measurement result expressed with uncertainty and to study the meaning of statistic and analysis of measurement uncertainty;
  • To study the fundamentals of metrology and metrological systems, Si units, traceability, etc.;
  • To learn the methods of measurements of the basic electrical quantities and caracteristics of the measurement transducers;
  • To introduce the basic principles of digitalization of the measurement signals in the time and frequency domain (sampling, A/D conversion techniques, etc.);
  • To get acquainted with the basic measuring instrumentation (multi-meter, electronic oscilosscope, universal counter, etc.) and with the avtomatization of the measurement systems (instrument and computer);
  • Introduction in the laboratory-instrumentation practices and to learn the security requirements and protection in measurements.

Intended learning outcomes:

  • To get information and adopt the basics of metrology;
  • Understanding of methods how to measure basic elektromagnetic and non-electric quantities;
  • To know how to express the mesasurement results with measurement uncertainty.

Learning and teaching methods:

  • Lectures,
  • laboratory tutorials,
  • laboratory work in small groups.
