Electrical Measuring Techniques
- to evaluate the measurement uncertainty
- specify the requirements for measuring elements
- explain the principles of operation of analogue and digital measuring instruments
- measure the electrical parameters using a digital oscilloscope, a suitable measuring instrument or bridge method
- measure the force in DC, single-phase and three-phase systems
- applied engineering approach to problem solving using acquired knowledge in physics, mathematics and electrical engineering basics
Forms of Teaching
Lectures are designed as 12 thematic units that are logically continue each other. Following the lectures, students are introduced to the problem of measuring the spectrum of different quantities, in a wide range of their values. The lectures dealt with the computational examples.Laboratory
Laboratory work provides 12 laboratory exercises that build on material from lectures. During the exercise, students have the opportunity to perform real measurements and apply the knowledge acquired in lectures.
