An Error Estimation Of The Current Sensors Of The Automated Control System Of The Technological Process Of Graphitation

摘要

The influence of structural factors on the error of current sensors with magnetic coil, which placed on the electrodes of the AC graphitization furnace, is researched. Quantitative estimation of error components, based on mathematical modeling of electromagnetic fields is performed. The calculation technique with the use of correcting coefficients, which ensures high accuracy of measurements is developed.
