Course detail

Měřicí metody v elektrotechnice

FEKT-BPC-MMEAcad. year: 2025/2026

The course provides students with a clear introduction to the principles and procedures used in the field of electrical measurements. Throughout the course, students will gain an understanding of different measurement methods, types of measuring instruments and measurement errors. The course also covers practical applications of measurement including small and large resistances, the use of bridge methods for measuring inductance and capacitance, the use of instrument transformers and current and voltage sensors, and other topics such as temperature, high voltage, and mechanical quantities. The last part of the course provides an introduction to computer-aided measurement and gives practical information on using LabView software to automate and process measurement data.
