Automated measurement uncertainty estimation - A new paradigm of measuring instruments and systems

Only complete expression of measurement result (measurement uncertainty included) makes possible correct interpretation of measurement results and reliable decision-making. Estimation of measurement uncertainty is complex and time consuming for some stand-alone digital instruments, and especially for indirect measurements results. It is possible to integrate calculation of measurement uncertainty into digital instrument containing processor. For direct and indirect measurements it is advantageous to develop appropriate software application for integration of digital instrument(s) and personal computer into an automated measuring system with the capability to display complete measurement result. The idea is illustrated on measurement of load-losses of power transformers using power analyzer. Software application for instrument transformers errors correction and reduction of measurement uncertainty is also briefly described.
