Measurements

This course covers the fundamental principles of measurements, measurement systems and measuring instruments, with emphasis on proper execution of measurements, evaluation of results, and understanding of traceability and measurement uncertainty. Students become familiar with basic concepts of metrology, measurement methods, and characteristics of measuring instruments, and gain insight into signal conditioning, acquisition and processing in analog and digital measurement systems. Particular emphasis is placed on practical aspects of electrical measurements and on linking theoretical concepts with laboratory work.

The course includes:

• introduction to measurement systems, standards, traceability, and the SI system,
• statistical treatment of results and evaluation of measurement uncertainty,
• measurement methods and static and dynamic characteristics of instruments,
• digital measurement procedures (sampling, quantization, Nyquist criterion),
• basic parameters of time-varying signals,
• signal conditioning, transducers, dividers, bridges, transformers, and current clamps,
• signal acquisition using oscilloscope probes and fundamentals of decision-making based on measurement results.

The course introduce basic knowledge of metrology and measurements of technical quantities. Objectives of the course are:

a) to study the fundamentals of metrology and metrological systems, Si units, connections with other fields of science;

b) to introduce the basic principles of measurement of most important quantities in engineering, properties of measurement signals;

c) to learn the approaches and methods of measurement of basic electric quantities and caracteristics of measurement transducers;

d) to extend the concepts of measurement and comprehension and interpretation of the measurement results;

e) to study the meaning of statistic and analysis of measurement uncertainty;

f) to prepare for laboratory practices and work;

g) to learn the security requirements and protection when using measurement instrumentation in connection with power supply.

Lectures, laboratory exercises, solving practical tasks (problems).
