Abstract

Instrument indicateur destiné à des mesures de puissance active et/ou réactive sur une ligne électrique comprenant un convertisseur destiné à envoyer, un milliampèremètre, une intensité caractéristique de la valeur de la puissance à mesurer. Cet instrument indicateur est par le fait que le secondaire 8 du transformateur d'intensité 7 et le secondaire 14 du transformateur de tension 13 sont tous deux du type à prise centrale et que le premier et le second circuit déphaseurs 9 et 15 comprennent chacun un circuit électrique constitué par une résistance 20, 21 et un condensateur 22, 23 montés en série, les bornes extrêmes 24, 25 du secondaire 8 du transformateur d'intensité 7 étant reliées aux bornes extrême du circuit électrique 20, 22 du premier circuit déphaseur 9, tandis que les bornes extrêmes 26, 27 du secondaire 14 du transformateur de tension 13 sont reliées aux bornes extrêmes du circuit électrique 21, 23 du second circuit déphaseur 15. Application à des lignes polyphasées.Indicating instrument intended for measurements of active and / or reactive power on an electric line comprising a converter intended to send, a milli-ammeter, an intensity characteristic of the value of the power to be measured. This indicating instrument is by the fact that the secondary 8 of the current transformer 7 and the secondary 14 of the voltage transformer 13 are both of the center tap type and that the first and the second phase-shifting circuits 9 and 15 each comprise a circuit electrical consisting of a resistor 20, 21 and a capacitor 22, 23 mounted in series, the end terminals 24, 25 of the secondary 8 of the current transformer 7 being connected to the end terminals of the electrical circuit 20, 22 of the first phase shifter circuit 9, while the end terminals 26, 27 of the secondary 14 of the voltage transformer 13 are connected to the end terminals of the electric circuit 21, 23 of the second phase shifter circuit 15. Application to polyphase lines.
