Abstract: The present invention provides a flange-mounted condition monitor (30) that can be mounted to an access flange (21) on an access opening (20) on the housing (13) of a generator (10). The condition monitor (30) forms an integral part of the generator (10) and eliminates the need for complex systems of pipes and valves for transferring hydrogen samples from the generator (10) to the condition monitor (30). The flange-mounted condition monitor (30) provides greater sensitivity to overheat conditions, significantly reducing the risk of dangerous hydrogen leaks and eliminating costs associated with installing and maintaining a remote condition monitor and also reducing or eliminating the false alarms associated with water that collects in the piping of a remote condition monitor.

Abstract: The present invention monitors RF emissions within a turbine generator. A coupling device provides a connection between preexisting thermal sensor leads and an RF monitor. Preexisting thermal sensor leads are connected to thermocouples and resistance temperature detectors during manufacture of the turbine generator. The RF monitor is used in the present invention to monitor RF emissions flowing in the thermal sensor leads thereby avoiding a need to retrofit RF sensors on the generator. The present invention also provides a capacitive coupling means between the thermal sensor leads and the RF monitor. The present invention also provides an inductive means to reduce interference from RF emissions having sources external to the generator.

Abstract: A sensor produces a signal indicative of the actual arrival time of each turbine blade at the sensor. A first circuit is responsive to the sensor for producing digital data representing the actual arrival time of each blade at the sensor. A second circuit establishes expected arrival times for each blade at the sensor. A third circuit is responsive to the digital data for generating a plurality of data entries each representing the difference between the actual arrival time and the expected arrival time. A fourth circuit stores the data entries in a first string having a plurality of dummy entries at the beginning thereof and at the end thereof and inserts into the string space saver characters in the event that the data entry for a particular blade is not produced. A fifth circuit establishes a running average value, over a plurality of data entries, for each data entry. The running average value is representative of common mode vibration. The average value is subtracted from its corresponding data entry to produce a second string wherein the entries in the second string are free of common mode vibration data.

Abstract: An optical vibration sensor is automatically calibrated by extracting a beat frequency vibration signal from a vibration signal produced by the optical vibration sensor, computing a resonant frequency of the optical vibration sensor using the beat frequency which has been extracted, and calibrating the optical vibration sensor based on the resonant frequency computed. The calibration method continuously compensates for changes in the resonant frequency due to temperature and mechanical changes of the optical vibration sensor. The optical vibration sensor is physically attached to an end-winding of an electrical generator.

Abstract: An ultrasonic cleaning apparatus and method is provided for a venturi flow nozzle which is mounted in a pipe having fluid flowing therethrough. The apparatus includes a plurality of ultrasonic transducers mounted in openings provided upstream of the venturi flow nozzle inlet. The transducers transmit ultrasonic waves directly into and thereby excite the fluid flowing through the venturi flow nozzle and create cavitation which cleans the nozzle. Additional transducers are preferably provided in the throat area of the venturi flow nozzle. In alternative embodiments, the transducers are mounted in high and low pressure taps associated with the venturi flow nozzle such that the transducers directly transmit ultrasonic waves into fluid flowing into the high and low pressure taps. The transducers may be mounted flush with the interior of the pipe or venturi flow nozzle, or the transducers may be mounted at a position spaced therefrom in the high and low pressure tap piping.

Abstract: A system for monitoring the temperature of a plurality of turbine blade shroud segments includes indicia carried by each shroud segment. A sensor produces input signals in response to the indicia. A temperature sensor measures the temperature of the sensor producing the input signals. A first circuit, responsive to the temperature sensor, corrects the input signals to compensate for the effects of temperature on the sensor. A second circuit determines the temperature of each shroud segment based on the corrected input signals.

Abstract: An improved tracer gas leak detection system and method for air inleakage testing of a turbine-condenser system quantified leak testing with two new elements: one, by providing discharge of a fixed, reproducible amount of tracer gas at a possible leak site, which is accomplished by controlling the flow rate, pressure and time interval of the discharge. Secondly, the total amount of tracer gas subsequently detected within the turbine-condenser is determined by integrating the detector response.
