A flux probe () for measuring the rotor flux of an electric generator (). The probe () is affixed to a probe carrier () and held within a stator coil slot () by affixing the carrier () to two opposing grooves () formed in sidewalls () of the slot (). One or more stator coils () are also disposed in the slot () and retained therein by a wedge () and corresponding spring () that applies an radially outwardly directed force to the coils (). In one embodiment the probe carrier () is affixed to a radially inwardly directed face () of the wedge ().

A method for measuring a tangential tightness of a stator coil within an armature slot of a stator assembly in an electric generator. The stator coil is excited to produce a vibratory response therein. The vibratory response of the stator coil is detected and a frequency response function of the vibratory response is determined. A tangential tightness of the stator coil within the armature slot is estimated based on the frequency response function of the vibratory response of the stator coil.

A system and method for monitoring the condition of a vibration sensor in a system. Vibrations are received in the system at one or more vibration sensors. Sensor data is output by the vibration sensor(s). The sensor data includes data representative of the vibrations in the system and data representative of a natural frequency of the corresponding vibration sensor. The sensor data output from the vibration sensor(s) is monitored, and upon a change in the data representative of the natural frequency of a vibration sensor, that vibration sensor is flagged.

An apparatus for containing a nut on a bolt including a housing having a main body, a proximal end and a distal end. A threaded aperture may be formed within the distal end of the main body for threading the housing onto the bolt. A flange extending from the housing that may engage the substrate when the housing is threaded over the bolt. At least one aperture formed within the flange for securing the housing to the substrate. A pair of housings may be placed adjacent one another and secured in a stationary position by a connector inserted through respective apertures formed in a flange of each housing. The connector may connect the housings together and be sized to prevent each housing from turning beyond an acceptable tolerance with respect to the other housing. The connector may be used to secure individual housings to other stationary components.

A method of removing a stator coil () from a stator core () of an electrical generator, including vibrating an unbonded portion () of the coil () until a resin bond material () between a bonded portion of the coil () and a surface () of the core () fails due to high cycle fatigue to free the coil () from the core ().

A standard, predetermined phase sequence of the three-phase voltage output of an electrical power generator, as produced through conventional main leads in the generator lead box which interconnect three (3) generally, axially aligned pairs of connectors of first and second sets, is selectively reversible by the utilization of crossed main leads between two adjacent pairs of the connectors of the first and second sets. Each of the crossed main leads includes opposite end portions aligned with the diagonally-related and interconnected pair of connectors of the first and second sets, the end portions having corresponding bends therein for smoothly contouring and integrally joining the central portions thereof, and the central portions have complementary outward bends in at least the mutual crossing portions thereof to maintain a predetermined, minimum distance therebetween so as to satisfy voltage strike requirements. Insulating support plates maintain the required minimum distance between the mutual crossing portions and special, directional ventilating ducts compensate for increased eddy current heating of localized areas of the lead box.

Method and apparatus for measuring the tightness of generator stator slot wedges and ripple springs with the rotor still in place. A wedge block having a hydraulic cylinder disposed therein is installed within the upper of a pair of parallel grooves in the stator slot. The hydraulic cylinder is activated to press down on a load plate, which in turn contacts a slot wedge within the other pair of parallel grooves. This is turn compresses the ripple spring between the slot wedge and the stator windings. A load cell measures the force required to compress the ripple spring, while four linear variable differential transformers measure the amount of displacement of the slot wedge. These two measurements are then used to derive a measurement for the tightness of the slot wedge and the ripple spring.

A resilient stator coil support bracket is provided particularly useful for large hydrogen innercooled turbine generators to give the end winding support assembly greater axial flexibility without substantially increasing the radial flexibility of the assembly. The support bracket includes an element secured to the core as well as an element secured to the brace that is radially outside each coil end turn with a sheet of resilient material therebetween, or there are two elements of the brace secured to the core with an intermediate element secured to the brace and the mating surfaces of all adjacent elements are spaced by sheets of resilient material, such as of an elastomer, that flexes in shear and compression modes. The bracket is tunable in the sense that the selection of the thickness and composition of the resilient material permits adjusting the natural frequency of the assembly to avoid resonance with the excitation frequency which such gas-cooled generators are sometimes susceptible. Also, the resilient bracket can be easily installed in the field to replace rigid brackets on machines in which the vibration problem has appeared.
