SECTION FOR ELECTRICAL QUANTITIES

OzaEV

Electrical measurements have a great impact on nearly all areas of research and development, industrial activities, quality of life and environment. Non-electric measuring quantities are converted into electrical quantities and as such are transformed, subsequently processed, stored and transmitted. Therefore, electrical measuring techniques play a key role in metrology. The first electrical measurements in the field of metrology in the Republic of Serbia was verification of electricity meters. In the XX century, at the end of 70’s, the first comparisons of DC voltage and resistance measuring standards with BIPM had begin, and first certificate provided traceability to the international measuring standards. Section for electrical quantities is accredited, which confirm the competence to perform testing of electricity meters, according to series of standards SRPS EN 62053 and SRPS EN 52470.

Activities and Tasks

The tasks of this section consists in research and development work in the area of electrical measuring. In the field of industrial and legal metrology, section for electrical quantities perform calibration of standards and measuring instrument testing. In addition to expert advice, the Section for electrical quantities provides a wide range of calibration and measurement capabilities, which are completely covered by quality management system.

Laboratories:

 

Transformation

Calibration and measurement capabilities (CMCs)

Testing of measuring instruments

The Section for electrical quantities performs testing of following instruments electricity meters

>measuring instruments for insulation resistance, loop impedance, resistance of earth connection and equipotential bonding, resistance to earth, and residual current devices testing. 

Projects

In the Section of electrical quantities are made following projects
