Abstract: Development of measuring equipment for current transformers accuracy testing at the Nikola Tesla Institute
Measuring current transformers are an important and inevitable element of AC current measurement techniques. They have been in use for more than a century. In parallel with the development of technical characteristics and improvement of current transformers, the measuring methods and equipment developed too. The measurement accuracy is the most important characteristic of measuring current transformers, since that is the important factor in the accurate billing of electricity.The tradition in the field of testing current transformer’s accuracy at the Electrical Engineering Institute Nikola Tesla is more than 60 years long. From the very beginning, the experts of the Institute have been active participants in the development of this field, both domestically and internationally. They have contributed to the development of measuring systems and standards for testing and calibration of current transformers, which have found application in laboratory calibration of the national metrology laboratories, as well as in industry.This paper provides an overview of the development of measuring methods for testing and calibration of current transformers, as well as a wide range of measuring devices and standards based on different measuring methods.

NANO-THINK project within the ERASMUS+ Virtual Exchanges program
The project “Learning critical thinking in science through the principles of nano-learning and virtual exchange” (NANO-THINK) was financed under the ERASMUS + Virtual Exchange program. The project brings together partners from the countries of the Western Balkans and Austria, and the Nikola Tesla Institute, as part of the University of Belgrade, is one of the participants. The coordinator of the project is the Faculty of Health Studies, University of Rijeka. The NANO-THINK project is a comprehensive initiative aimed at creating a specialized program that encourages critical thinking in science. The principles of virtual learning and so-called focused nano-tools will be used in the development of the program, so that the learning experience will be attractive, interesting and effective for modern generations of students.
