Abstract

Power quality analyses in the last years has assumed more and more heaviness in industrial environments, due to the presence of non-linear loads: they require suitable and precise measuring instrumentation. Nevertheless, while there are lots of power quality standards fixing high frequency limits for harmonic analyses, there is a lack of standards concerning transducers calibration at amplitude and frequency different from the rated ones. Therefore in this paper a fully automated measuring station for the calibration of voltage transducers in wide amplitude and frequency ranges is discussed. As an application, the results of the calibration of a commercial transducer are presented: they are used to implement a time-domain procedure for real-time correction of the frequency response of the calibrated transducer.
