Measurement in Electrical Engineering
FEKT-BMVAAcad. year: 2018/2019
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.
Learning outcomes of the course unit
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.
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.

Planned learning activities and teaching methods
Techning methods include lectures, computer laboratories and practical laboratories. Course is taking advantage of e-learning.
Assesment methods and criteria linked to learning outcomes
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.
Language of instruction
1. Principles of correct measurement, standards of measuring electrical quantities.
2. Evaluation of the accuracy of analogue and digital instruments.
3. Uncertainties of direct and indirect measuring methods.
4. Measuring amplifier, its characteristic and use in measuring technology, converters for the realization of mathematical operations.
5. Analogue measuring instruments.
6. Digital measuring instruments, sampling, A/D converters, characteristics.
7. D/A converters.
