Electrical Measurements (3cr)

Objective

After completing the course, the student is able to perform basic electrical and process engineering measurements safely and correctly. Based on the obtained measurement results, the student can identify and locate potential faults and tune the equipment to operate in an energy-efficient manner. The student takes sustainable development principles into account in both measurements and equipment use – for example, by selecting measurement devices that are long-lasting and maintainable. The student is able to consider the effects of external disturbances on measurement results while carrying out measurements. In addition, the student is familiar with the characteristics and application possibilities of computer-based measurement devices in various contexts.

Content
