Automated Estimation of Measurement Uncertainty

Only complete expression of measurement result makes possible correct and reliable decision making. Complete measurement result is the range of values determined with measured value, determined with measured value, measurement uncertainty and measurement unit. Estimation of measurement uncertainty can be complex and time consuming for some digital instruments alone, and especially for results of indirect measurements. Using software it is possible to integrate digital instruments (with communication interface) and PC in an automated measuring system. Present automated measuring systems have features of automated measurements, storage of data and report generation. To adopt these systems for a new demand of complete measurement result presentation, the additional steps are necessary: design of measurement model, measurement uncertainty analysis, design of algorithm for uncertainty estimation, and finally, automation of uncertainty calculation and presentation of complete measurement result. The process of complete measurement automation is illustrated on testing of power losses of power transformers with power analyser (PA).
