Course detail

Measurement in Electrical Engineering

FEKT-BPC-MVAAcad. year: 2023/2024

The course is focused on measuring electrical, magnetic, and non-electrical quantities. In the first part of the semester, students are introduced to the basics of metrology in order to be able to evaluate the accuracy of measuring methods and measuring instruments, both analogue and digital. In subsequent sections the principles, structure and characteristics of measuring instruments, sampling, A/D and D/A converters, oscilloscopes and counters are explained. Almost half of the semester is devoted to methods of measuring voltage, current, frequency, time interval, phase, power, resistance, capacitance, inductance and resonant frequency, magnetic quantities, and non-electrical quantities.
In laboratory exercises, students verify in practice the knowledge acquired in lectures: implementation of measuring methods, selection of appropriate measuring equipment, measurement proper, and accuracy evaluation via calculating the uncertainties.

Entry knowledge

Knowledge at the level of secondary education and completion of obligatory courses taken in the first year of study at FEEC are required. Emphasis is placed on the knowledge of basic statistical methods, theoretical electrical engineering, signal processing, and analogue technology.

Rules for evaluation and completion of the course

The student can achieve:
- up to 20 points for the correctly prepared and in time submitted jobs
- up to 10 points for the absolved test measurement,
- up to 70 points for the exam.
The exam is focused on verifying the student’s orientation in the problematic of accuracy, construction, and characteristic of measuring instruments and methods.

In order to receive credit, all lab reports must be turned in by the regular/corrective deadline. To pass the course, the cumulative points earned during the semester + from the exam must be a minimum of 50 points.

Attendance at laboratory exercises is compulsory; authorized absence from laboratory exercises can be made up for, after agreement with the teacher (usually in the last week of the semester).


The aim of the course is to provide students with information about methods for evaluating the accuracy of instruments and methods, about measuring instruments and methods for measuring active and passive quantities, as well as magnetic and non-electrical quantities.
Students who complete this course are able to:
- Evaluate the accuracy of the measuring method and instrument.
- Explain the construction and characteristics of standards of measuring el. quantities.
- Be knowledgeable about the choice of suitable measuring techniques and methods, realise measuring tasks and evaluate measurement accuracy.
- Operate basic types of measuring instruments, oscilloscopes and counters.
- Explain the principle of converters realising mathematical operations, A/D converters, and D/A converters.
- Explain the principle of analogue and digital measuring instruments, evaluate their advantages and disadvantages.
- Be well informed in the choice of a suitable method for measuring active and passive electrical quantities, evaluate their advantages and disadvantages.
- Be well informed in the choice of a suitable method for measuring magnetic and non-electrical quantities.
