Abstract: Apparatus (12) to measure blade vibration in a gas turbine engine (8). An illumination source (20) generates a sequence of illumination bursts in a field of view capturing a passing rotating blade (10) of the gas turbine engine. An imager (22) generates image data including a series of images capturing views of the passing rotating blade. The images are exposed in response to respective illumination bursts. A controller (30) is configured to process the series of images to identify one or more vibration modes of the rotating blade.

Abstract: A method is provided for monitoring velocity of a fluid flow through a predetermined fluid flow space. A fiber optic conductor includes a flow measurement portion defining an elongated dimension extending across a portion of the fluid flow space. The fluid flow in the fluid flow space causes the measurement portion of the fiber optic conductor to flex in a direction transverse to the elongated dimension. Optical radiation is supplied to the fiber optic conductor, and optical radiation is received from the fiber optic conductor after the supplied optical radiation has passed through the measurement portion. The received optical radiation is analyzed to effect a determination of a flow velocity of the fluid flow.

Abstract: A method and apparatus for monitoring blade vibrations in a turbine engine having blade tip target portions associated with blades. An illumination conduit including a plurality of optical fibers conveys light from a light source to a transmission end of the optical fibers where the light is focused to define an axially elongated projected image. The blade tip target portions pass through the projected image and reflect light to receptor ends of a plurality of optical fibers defining a detection conduit for conveying the reflected light to a processor. The transmission ends and receptor ends of the optical fibers are configured as a narrow rectangle to define a probe end for receiving reflected light at different axial locations along the probe end, and to detect blade passing events defined by passage of either or both a blade leading edge and a blade trailing edge.

Abstract: A partial discharge coupler for detecting partial discharges in a conductor includes a frequency dependent network, a differential amplifier and a frequency selective coupling component. The frequency dependent network includes a first filter component, a fuse component and a load component, typically coupled together in series with reference to a first ground. The first filter component filters the high voltage, low frequency alternating current signal carried by the conductor from the load component and passes high frequency partial discharge pulse signals to the load component. The frequency selective coupling component couples in series between the differential amplifier and the load component. The output of the differential amplifier is configured to provide an output that is isolated from the ground connection for communicating detected partial discharge signals to partial discharge test equipment.

Abstract: Electrical generators used for power generation typically operate at high voltage. The High operating voltage results in a severe electrical stress environment for the generator conductor insulation system. The high electrical stress cal lead to a phenomena such as corona, partial discharge and arcing that can cause damage to the insulation and conductors. Disclosed is a novel method and system of detecting partial discharge activity within an electric generator. The method employs at least two Rogowski loops non-contactingly surrounding individual iso-phase bus conductors, where the loops are wired in differential mode to detect fast moving electrical pulses indicative of partial discharge.

Abstract: A measurement device for measuring the wear of turbo-machine components to reduce the likelihood of component failure while a turbine-machine is at load. The measurement device is capable of measuring and calculating a distance between surfaces while the turbo-machine is at load. The distance may be compared with a measurement taken of the same location at another time to determine wear of a surface remote from the location of the measurement. The measurement device may be configured such that multiple measurements may be made on a single turbine engine by moving the measurement device from location to location.

Abstract: A system (10) for imaging a rotating turbine blade (20) includes an image projector (12) receiving a moving image of the rotating blade and projecting a movement-compensated image. The system also includes an image receptor (14) for receiving the movement-compensated image. A sensor (16) is provided for generating information (28) indicative of a velocity of the rotating turbine blade and a processor (18) generates a drive signal (30) responsive to the information for controlling a position of the image projector. The image projector is controlled to receive the moving image at a desired angular position and to project the movement-compensated image to the image receptor so that the movement-compensated image appears stationary relative to the image receptor.
