Specific course objectives

The goal of this course is to provide an introduction to industrial electrical measurements for low-voltage circuits with an experimental approach. We consider only dc and sinusoidal quantities, as well as symmetric systems in stationary regime. The most important formative objectives are the knowledge of the concepts of measurement and measurement uncertainty, the knowledge of the main measurement methods for electrical quantities both theoretically and practically, as well as the knowledge of the main measurement instruments for electrical quantities both theoretically and practically.

Course programme

The course can be divided in two parts, the first, more theoretical, devoted to the definition of the concepts of measurement and measurement uncertainty, as well as to the description of the basic instruments, while the second, more practical, focused on the measurement methods and their application.

First part
Measurement theory and instrumentation

• General concepts
• Measurement uncertainty
• Analog measurement instruments
• Analog-to-digital conversion
• Digital measurement instruments
• Criteria for the instrument choice

Second part
Measurement methods

• Measurement methods for dc quantities and use of the instrumentation
• Measurement methods for ac monophase quantities and use of the instrumentation
• Measurement methods for ac polyphase quantities and use of the instrumentation
• Bridge methods for dc measurements and use of the instrumentation

Course entry requirements

Basic knowledge of mathematics, statistics, physics and electrotechnics.

Suggested reading materials

The lecture notes (P. Malcovati, Misure Elettriche) and the slides used during classes (both available on-line at http://sms.unipv.it/misure) cover the entire program of the course. Additional informations can be found in:

Testing and exams

There will be a witten test at the end of the course. Moreover, the students will prepare reports on the activities carried-out during the experimental laboratory exercises. For the students that will have performed the written test and attended the laboratory exercises, the oral exam will consists in a discussion on the written test and the prepared reports. For the students that will not have performed the written test and/or attended the laboratory exercises, the exam will consist of an oral test on the whole program of the course.
