Аналіз метрологічних характеристик вимірювальних перетворювачів потужності

Abstract

To construct the structural diagrams of the power measuring converters, methods of digital -analog and frequency-pulse multiplication of current and voltage signals, which are consumed by the drive of the main movement of the metal -cutting machine, are proposed. Based on the methods of information theory, in particular, the information approach, a meth d for statistical processing of experimental data has been developed with the aim of establishing the errors of the proposed power transducers. It is established that the metrological characteristics of the power measuring converters satisfy the accuracy requirements.
