Abstract

Ein System (100) zur Detektion einer Leckage in einer Dampfturbine (110) umfasst eine Infrarotbildgebungsvorrichtung (120), die dafür eingerichtet ist, wenigstens einen Abschnitt der Dampfturbine zu scannen und mit einer Benachrichtigungsvorrichtung zu kommunizieren. Die Infrarotbildgebungsvorrichtung umfasst einen gekühlten Detektor (122) und einen Filter (124) mit einer Spektralempfindlichkeit oder einem Durchlassband zwischen etwa 2,5 µm und etwa 8 µm. Die Leckage wird auf der Benachrichtigungsvorrichtung (160) angezeigt, und der gekühlte Detektor wird auf zwischen etwa –80 °C und etwa –200 °C gekühlt. Die Dampfturbine kann sich während der Detektion der Leckage im zugeschalteten Zustand befinden.
