METRICA, l’archivio istituzionale della produzione scientifica dell’Istituto Nazionale di Ricerca Metrologica, ha lo scopo di raccogliere, documentare, conservare e pubblicare, anche ad accesso aperto, i prodotti della ricerca dell’Ente.
METRICA utilizza la piattaforma IRIS (Institutional Research Information System) sviluppata da Cineca.
EnglishThe phase and ratio errors of transducers for distribution electrical grids can be measured, in a wide frequency range, by a synchronized couple of digitizers Agilent 3458A working in DCV mode. The high metrological performances of the digitizers is degraded by the input low pass filter cut-off frequency, which depends on the selected range. This paper proposes a technique to identify and model, for each range, the filter complex function up to several tens of kilohertz. First tests show its potentiality in reducing the errors introduced by the digitizers, when set on different ranges, in frequency calibration of voltage/current transducers.

| Abstract: | The phase and ratio errors of transducers for distribution electrical grids can be measured, in ...a wide frequency range, by a synchronized couple of digitizers Agilent 3458A working in DCV mode. The high metrological performances of the digitizers is degraded by the input low pass filter cut-off frequency, which depends on the selected range. This paper proposes a technique to identify and model, for each range, the filter complex function up to several tens of kilohertz. First tests show its potentiality in reducing the errors introduced by the digitizers, when set on different ranges, in frequency calibration of voltage/current transducers. | |
