Abstract

Un dispositivo de compensación de transformadores de corriente, pinzas y transductores magnéticos de corriente, que mejora su performance de exactitud, caracterizado por un dispositivo totalmente externo que disminuye la corriente magnetizante, sin necesidad de ningún arrollado auxiliar ni dobles núcleos. El dispositivo evalúa la corriente de la rama magnetizante, conectándose solo a los bornes de salida del transformador. Este computo se realiza a partir de la medida de la corriente y tensión secundarias. A partir de la evaluación de la corriente magnetizante, una fuente de tensión controlada externa de valor Vc, disminuye su valor. Los parámetros del circuito de control se diseñan en función de la resistencia del arrollado secundario, de modo que la tensión Vc imponga una tensión V2 que disminuya la tensión en la rama magnetizante y por consiguiente su corriente.A compensation device for current transformers, clamps and magnetic current transducers, which improves its accuracy performance, characterized by a totally external device that reduces the magnetizing current, without the need for any auxiliary winding or double cores. The device evaluates the current of the magnetizing branch, connecting only to the output terminals of the transformer. This computation is carried out from the measurement of the secondary current and voltage. From the evaluation of the magnetizing current, an external controlled voltage source of value Vc, decreases its value. The parameters of the control circuit are designed as a function of the resistance of the secondary winding, so that the voltage Vc imposes a voltage V2 that decreases the voltage in the magnetizing branch and consequently its current.
