IEEE/IEC P61869-105 IEEE/IEC Draft Recommended Practice for Uncertainty Evaluation in the Calibration of Instrument Transformers

IEEE/IEC P61869-105 IEEE / IEC Проект Рекомендуемая практика для неопределенности оценки в калибровке измерительных трансформаторов

This recommended practice defines a common viewpoint of the evaluation of uncertainty in calibration and its application in testing procedures for Instrument Transformers (ITs). Definition of how to take into account the sources of uncertainty of the measurement system and how to combine their effects in order to evaluate the uncertainty on the measurement results. The recommended practice also presents the common requirements to be used during tests for assessing the accuracy of ITs.
