Abstract

Un método para la prueba en línea de un sistema de disparo de emergencia de una central eléctrica de turbina de incluye un canal para drenaje para fluido hidráulico mantenido a una presión previamente definida, una válvula normalmente cerrada en el mismo, medios para mantener bajo presión de fluido la válvula cerrada en condiciones normales de funcionamiento de la turbina y medios para liberar tal presión para abrir la válvula al producirse una contingencia indicadora de una condición de funcionamiento inseguro de la turbina.
