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 calibrations of DC voltage and resistance standards with BIPM began and first certificate provided traceability to the international 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.

Within European Association of National Metrology Institutes - ЕURАМЕТ this section operates through the participation in the activities of the Technical Committees for Electricity and Magnetizm (TC-EM), Technical Committee for interdisciplinary metrology (TC-IM) and 3 Technical Subcommittees (SC-LF, SC-DC & Quantum Metrology, SC-Power and Energy).

 

Activities and Tasks

The section for electrical quantities is responsible for the practical realization of one of the seven basic units of the SI system: the ampere – the unit for electric current.

The tasks of this section are research and development in the field of electrical quantities. In the field of industrial and legal metrology, section for electrical quantities perform calibration of standards and measuring instrument testing as well asmetrological expertises 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.
