Metrology Fundamentals

Course Description

Fundamental terms of metrology. Measurand, influencing quantities and result of measurement. Least squares theory. Assessment of the uncertainty of measurement and expression of the results. International System of Units (SI). Metrology infrastructure and traceability. Basic analog and digital measuring instruments. Principles of work, characteristics and applications. Measurement of voltage, current, resistance, power and energy. Measuring bridges. Grounding, shielding and interference protection. Computer based measurements. Virtual and distributed measuring systems. Communication protocols connecting computer and instruments. Software for acquisition and analysis of results of measurement.

General Competencies

The students will have a good understanding of the importance and application of metrology and measurement in the electrical engineering. They will have a good basic knowledge of metrology terminology, units, and the analysis of the measurement results, as well as a of different types of measuring instruments and measurement systems controlled by the computer, used in the methods of measurement of electrical quantities.
