Phasemètre étalon primaire à commande numerique au BNM-LCIE

摘要

The BNM-LCIE realized a new measuring equipment intended to provide a calculable reference for the calibration of phasemeter and phase shift devices. The bench is set up around a main device comprising a network, the phase displacement of which can be derived from the known characteristics of its components and hence used to determine the phase angle between the input voltages. The ranges of use extend up to 1 000 V for voltage and from 20Hz to 20 kHz for fre-quency.
