Abstract: A method for inspecting a wye ring in a generator includes the steps of dismantling the generator to gain access to the wye ring and at least a portion of a rotor, applying a test signal to the rotor and measuring an inductive voltage at two or more locations near the wye ring. A comparing step compares results from the measuring step to determine if a fault exists in the wye ring. A predetermined difference in inductive voltage measurements indicates presence of the fault.

Abstract: A method for detecting leakage at a fluid connection for a gas turbine fuel supply system is disclosed herein. The method includes closing a flow control valve at an upstream end of the fuel supply system and pressurizing the fuel supply system with a compressed medium via a compressed medium supply to a target pressure. The target pressure is less than a pressure threshold of a check valve that is disposed downstream from the compressed medium supply and upstream from a corresponding combustor of the gas turbine. The method further includes pointing a receiver portion of an ultrasonic detection device proximate to at least one tube fitting of the fuel supply system located between the flow control valve and a combustor which is fluidly coupled to the fuel supply system. Detection of an increase in sound level and/or the sound of popping at the tube fitting is indicative of a leak at the tube fitting.

Abstract: Various aspects include methods of inspecting a substantially round hole in a material. One method can include: feeding a probe axially into the substantially round hole until the probe completely passes through the substantially round hole while the probe is activated; rotating the probe at least ninety degrees around a primary axis of the substantially round hole after feeding the probe completely through the substantially round hole; removing the probe axially from the substantially round hole after rotating the probe at least ninety degrees while the probe is activated; and compiling at least one of eddy current data or ultrasound data about the hole from the feeding of the probe axially into the substantially round hole and the removing of the probe axially from the substantially round hole.

Abstract: An inspection system for a cylindrical member includes at least one retention member positionable about at least a portion of a circumference of the cylindrical member. The inspection system also includes a positioning system and at least one housing. The at least one housing is coupleable to the at least one retention member at each of a series of circumferential inspection locations. The at least one housing includes at least one probe. The positioning system cooperates with the at least one retention member to position the at least one probe at each of the circumferential locations. The at least one probe is configured to send and receive a signal through an interior of the cylindrical member.

Abstract: The method includes positioning a probe of the phased array ultrasound system on the mounting portion of the anisotropic rotor blade at the axial centerline. The method further includes scanning a sector of the anisotropic rotor blade along the axial centerline with the probe of the phased array ultrasound system. The method further includes determining a magnitude and a time delay of an echo signal corresponding with a geometric fiducial marker. The method further includes adjusting a position of one of the anisotropic rotor blade or the probe based on the magnitude and/or the time delay of the echo signal corresponding with the geometric fiducial marker. The method further includes repeating the scanning, determining, and adjusting steps until the magnitude and the time delay of the echo signal corresponding with the geometric fiducial marker is within a predetermined maximum echo range. The method further includes scanning the anisotropic rotor blade for defects.
