چکیده
− Power quality measurement analysis of the electrostatic precipitator in thermal power plant under different working conditions is presented in the paper. Control of electrostatic precipitator is realized by digitally controlled antiparallel thyristors. In the first regime (continual) the constant firing angle of thyristor is set in dependence of the reference current. In other regime (intermittent) the ON/OFF period is set. For both control strategies the measurement of the content of higher harmonic of voltage and current is performed. Analysis of the measured results is done according to the methodology based on EU power quality standard EN 50160. The plant under investigation is electrostatic precipitator in the largest thermal power plant “Nikola Tesla A” in Serbia, but the obtained results could be used for any similar power plant.

− The assessment of the geometry of artefacts in length metrology is concerned with estimating dimension, form and roughness. While all three are positive quantities, the evaluation of form and roughness are problematic, mainly because the values of the parameters to be measured are often of the same order as the measurement uncertainty. Furthermore, random effects associated with a measurement...

Linear Regression Analysis (LRA) is one of the statistical tools most intensively used in all branches of science, with many applications in the study of measurement processes and is therefore important in metrology. The implementation of metrology in quality systems, led to a widespread evaluation of measurement uncertainties based on the GUM uncertainty framework (Guide to the Expression of U...

− The measurement of air shock wave pressure is a typical problem of transient measurement. Because the measurement data in many cases is used to judge the quality of a product, or as a basis for changes being made during a development phase, uncertainty analysis or assessment of measurement data takes a very important role in the process of reporting experimental results. It is very difficult ...
