Abstract

Sistema, aparato y procedimiento para reducir una corriente de irrupción en un transformador trifásico.#Un sistema para reducir a corriente de irrupción en un transformador trifásico tras la energización del transformador mediante una tensión trifásica aplicada que utiliza un circuito de preflujo para establecer niveles de flujo residual en los segmentos de núcleo de las espiras primarias del transformador que están cerca de los niveles de flujo prospectivo establecidos en los segmentos de núcleo mediante la tensión aplicada. El circuito de preflujo incluye un condensador de fijación previa que, después de cargarse a un nivel de tensión predeterminado, se descarga en serie a través de dos de las espiras primarias para establecer los niveles de flujo predeterminados en los segmentos de núcleo de las dos espiras, y un nivel de flujo reducido en el segmento de núcleo de la espira primaria restante. El transformador se energiza en el instante de la tensión de fase del pico referenciado de manera positiva a la tercera espira primaria, de manera que el flujo prospectivo y el flujo residual se aproximan a un nivel casi igual en la totaliada de los tres segmentos de núcleo y la corriente de irrupción es reducida.
