摘要： 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.

摘要： Embodiments of the disclosure relate to ultrasonic inspection of turbine components. In one embodiment, a method for ultrasonic inspection of a turbine component can include mounting at least one array of transducer elements to the turbine component, (a) separately pulsing a transducer element of the at least one array of transducer elements to transmit a signal to the turbine component, (b) capturing reflected signals from the turbine component at each transducer element in the at least one array of transducer elements, repeating (a) and (b) for each of the other transducer elements in the at least one array of transducer elements, maintaining a constant relative position of the array of transducer elements with respect to the turbine component, analyzing the captured reflected signals using a computer, generating an image of the interior volume of the turbine component by reconstruction of the captured reflected signals and based at least in part on detecting an anomaly in the image of the interior volume of the turbine component, identifying at least one defect or failure in the turbine component.

摘要： 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.

摘要： Ultrasonic detection methods are disclosed. The method includes providing an ultrasonic detection system having a transmitting phased array device and a receiving phased array device. A phased array wave is transmitted through a revolutionary body from the transmitting phased array device to the receiving phased array device, thereby obtaining ultrasonic detection information about the revolutionary body. In another embodiment, the method includes positioning the transmitting phased array device and the receiving phased array device on a periphery of a turbine rotor, transmitting a phased array wave into the turbine rotor, the phased array wave not reflecting off of a reflecting feature, adjusting the positioning of the transmitting phased array devices on the periphery of the turbine rotor, and transmitting the phased array wave into the turbine rotor, the phased array wave reflecting off of a reflecting feature. The reflected phased array wave is received by the receiving phased array device.
