Course detail

Measurement in Electrical Engineering

FEKT-KMVAAcad. year: 2017/2018

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.

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.

Co-requisites

Not applicable.

Planned learning activities and teaching methods

Techning methods include lectures, computer laboratories and practical laboratories. Course is taking advantage of e-learning (Moodle) system. Students have to write a single project/assignment during the course.

Assesment methods and criteria linked to learning outcomes

The student can achieve:
- up to 20 points for correctly prepared and in time submitted homework,
- up to 10 points for the correctly prepared and in time submitted reports from laboratory measurements,
- 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.
