Abstract

Transformador de medición para comparar una corriente que circula por un conductor con una corriente teórica, con un circuito magnético formado por un núcleo anular, con un conductor rodeado por tal núcleo anular y por el que circula una corriente, con un bobinado secundario dispuesto sobre el núcleo anular y con un elemento de medición de campo magnético dispuesto en un entrehierro del núcleo anular y sensible al campo magnético de tal entrehierro. A los fines de detectar también con seguridad desviaciones de alta frecuencia de un valor teórico con un transformador de medición de tal tipo se sugiere, de acuerdo con la invención, prever una unidad de determinación de valores teóricos para aplicar en el bobinado secundario una corriente teórica. El transformador de medición de acuerdo con la invención se emplea, con preferencia en la medición de la corriente de salida de un alternador para una planta de energía eólica.
