Abstract: Fail-safe bypass monitoring system for measuring volumetric flow rates in a pipe which normally carries a relatively low pressure, low volume gas flow. The system comprises a water trap valve positioned to seal off relatively low pressure gas flow through the pipe and divert the gas flow through a flowmeter. The flowmeter receives gas flow from the pipe adjacent a first end of the water trap valve and returns gas flow to the pipe adjacent a second end of the water trap valve. The water trap valve always passes relatively high pressure gas directly through the pipe.

Abstract: Apparatus which measures temperature in the high voltage environment of an electrical generator includes a temperature sensing element which includes a polarizing filter rotatable as a function of temperature. Light from a source is passed through the filter and the polarized light is again polarized through the use of a constantly rotating second polarizing filter behind which is a detector operable to provide an AC signal as a function of the doubly polarized light intensity. A reference beam is passed through the second rotating filter as well as a manually rotatable polarizing filter and is detected so as to provide a second AC signal. After an initialization, the AC signals are compared in phase, with the phase difference between them being a function of the temperature being measured.

Abstract: A blade vibration monitor backpressure limiting system (BVMBLS), that in addition to direct blade vibration and condenser backpressure monitoring utilizes other plural types of other parallel, real time monitored power plant operation state (OS) information that influences blade vibration. The system references previously stored information in an information storage device that associates respective types of monitored OS information with blade vibration. The BVMBLS determines in real time a likelihood of whether any of the monitored operation states, alone or in combination with other types of monitored operation states, is indicative of a turbine blade vibration safe operation (SO). The BVMBLS determination is utilized to increase or reduce power generation load incrementally so that power efficiency and maximum load is enhanced while turbine blade vibration is maintained in a safe operation state. The previously stored information is updated to new association information.

Abstract: A sensor includes a housing adapted to be secured to a component within a system to be monitored by the sensor, an optical fiber, and a membrane spring assembly. The optical fiber includes a sensing portion containing a fiber Bragg grating that is able to undergo expansion and contraction resulting from movement of the optical fiber at a second location relative to a first location. The membrane spring assembly includes a membrane disc, wherein movement of a central portion thereof causes corresponding displacement of the optical fiber at the second location to cause expansion and contraction of the sensing portion of the optical fiber containing the fiber Bragg grating, which expansion and contraction effects a change in a light wavelength reflected by the fiber Bragg grating. The light wavelength reflected by the fiber Bragg grating can be used to measure movement of the central portion of the membrane disc.

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 method and apparatus for monitoring vibrations in a blade structure of a turbine including generating signals from a probe located adjacent to a radial outer edge of the blade structure to provide signals corresponding to vibrations at predetermined locations along the tips of the blades. A leading edge of a blade tip is detected during a blade tracking operation, and a known location along the length of the blade tips is monitored during a vibration measurement operation. The measurement operation may be performed simultaneously with the tracking operation to provide measurements as the axial location of the blades change during transitional modes of operation of the turbine.
