Ecological Systems and Devices Annotation << Back METROLOGICAL ANALYSIS OF TEST RESULTS FOR RESIDUAL CURRENT DEVICE G.N. Akhobadze A method for metrological analysis of test results for Residual Current Device is proposed. A number of multiple direct measurements of breaking differential current at its constant value are described. Asymmetric current values measured depending on loading and voltage are shown. Using the test results, the arithmetic mean and the mean square deviation of the breaking differential current are estimated. Applying the table method and the three-sigma one, miscalculations and their absence are revealed in some test results. Confidence limits and intervals of the systematic error, arithmetic mean, and mean square deviation are computed. Keywords: current; analysis; deviation; error; confidence interval; method; miscalculation. DOI: 10.25791/esip.06.2019.663 Contacts: E-mail: ahogur@yandex.ru Pp. 40-46.
