THE ELECTROMETRIC AC-DC TRANSFER STANDARD AS PRIMARY STANDARD AT IEN FOR AC VOLTAGES FROM 300 V TO 1000 V

U. Pogliano, G.C. Bosco

Abstract

An electrometric AC/DC transfer standard has been built, which compares the equivalence between an AC and a DC voltage by an attracting force sensed by an analytical scale. The functionality and the stability of the instrument have been tested and the electromagnetic and mechanic effects have been analysed. Comparisons with thermal converters have shown that this instrument can be conveniently used to maintain the traceability for voltage beyond 300 V, in the frequency range from 1 kHz up to 100 kHz.
