Data Fusion in Phase Angle Measurement System

Ryszard Sroka

Abstract

From many years in various science and technical areas there are introduced data fusion methods, lately also in metrological applications. Now there are conducted investigations connected with determining of importance of data fusion in classical metrology, complex measurement systems and also in measuring-control, diagnostic, classification systems, etc. The paper presents author’s point of view on data fusion process. It pointed that using of data fusion methods in metrology is possible and purposeful. Data fusion process in the paper is presented on example of the phase angle measurement method with improved tolerance on harmonic distortions. The purpose of data fusion in this case is reduction of basic error of analysed method. It has been proposed introduction of an additional data processing line (as a source of new information in measurement process), and shows a method for combining information acquired from these two lines. The analysis presented in the paper indicates that using the method of information combining (data fusion) in measurement applications brings measurable effects (basic error of considered system lowered more than 200 times).
