Errors of New Transformer Converters Measuring Angular Displacement Difference

Abstract

The article identifies and evaluates the error sources of transformer converters designed to measure the angular displacements of two objects in the newly developed and automatic control and management systems and their difference. Analysis of error sources showed that their theoretical, technological, and operational sources are the main error sources, while internal, external, and mode sources are additional error sources. Theoretical sources of error usually arise from the fact that the measuring device being studied is not taken into account in full all the laws in its work activities, and technological sources are from the fact that the technology for making a measuring device has not been improved. Errors that arise in the process of assembling and configuring the structure are also included in the sources of technological error. The error due to the nonlinearity of the static characteristics of the new transformers is greater than other main error sources, the errors due to changes in the amplitude, frequency and load resistance of the excitation current are greater than other additional error sources, and the calculated errors of the two new transformers 5% and 1.0%, respectively.
