Research of Error Probability Characteristics of Voltage Measuring Instruments

The graduate qualification work is devoted to the study of probabilistic characteristics of errors of voltage measuring instruments. In this work were performed analysis of sources on the laws of error distribution, methods of their identification; studied normative documents on metrological characteristics of SI, including SI of voltage measurement, as well as methods of their determination; nomenclatures and characteristics of measuring devices and converters available in UL “Metrology and Measurement Technologies”; experimental research and processing of experimental results using statistical methods and tools. Qualitative studies of voltage measurements based on the selected methods were carried out and the obtained results were analyzed. While performing the work, an auxiliary file was developed to facilitate the calculations, which will be useful in the study of measurement errors in the future.
