Abstract

Método de estimación de resistencia de falta ante faltas a tierra en devanados rotóricos de máquinas síncronas. La presente invención permite la estimación de la resistencia de falta ante defectos a tierra en devanados rotóricos de máquinas síncronas alimentados mediante rectificadores conectados a un transformador. El método presenta la ventaja de poder conocer la magnitud del problema que afecta a la máquina, ya que cuanto mayor sea la resistencia de falta, menor será la corriente de defecto. La estimación se basa principalmente en el análisis de las componentes armónicas de la tensión en la resistencia de puesta a tierra.
