- Abstract:
- The calibration laboratories accredited according to the standard ISO/IEC 17025:2017 should continuously monitor the validity of measurement results. By ensuring the validity of calibration results, the laboratory also monitors its own performance. There are several different techniques for confirming the validity of results and they are a matter of choice and capability of the accredited laboratory. The paper describes two different methods that the Laboratory for testing and calibration of the Nikola Tesla Institute of Electrical Engineering uses in intra-laboratory comparison as a technique for ensuring the validity of current transformer calibration results. Statistical processing of the obtained results shows that the En number at all measurement points is satisfactory, which confirms the competence of the Institute's Laboratory in the field of current transformer calibration.
