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.
EnglishAbstract: A set-up for the measurement of the frequency response of voltage measurement transformers under actual waveform conditions is presented. It is based on a two steps procedure that makes use of high voltage gas insulated capacitors and a digital bridge. It allows calibrations using distorted waveforms, with a fundamental tone at medium voltage level and superimposed harmonics up to 20% and 15 kHz. Some experimental tests are presented. Different frequency behaviors of voltage transformers are found with: different capacitive loading, different type of characterization (low voltage or medium voltage) different harmonic order.
