Abstract

The article addresses the issues of metrological support of information-measurement systems used for monitoring the technical condition of electrical machines. The main sources of systematic and random errors in measurement channels of currents, voltages, and winding temperatures are analyzed, as these errors directly affect the reliability of diagnostic decisions. Mathematical models of measurement channels are developed, taking into account dynamic operating modes of electrical machines and thermal instability of measurement system components. A comprehensive approach to evaluating the total measurement error of the information-measurement system and its influence on the accuracy of technical condition assessment is proposed. The obtained results can be applied to improve diagnostic reliability, measurement accuracy, and operational efficiency of electrical machines in industrial electric drive systems.
