摘要： 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.

摘要： 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.

摘要： Fault analysis and detection involving a generator neutral ground includes monitoring a voltage waveform across a neutral grounding transformer of a generator. During monitoring of the voltage waveform a sample of the voltage waveform is acquired. Previously, a number of similar past samples of the monitored waveform were acquired and stored as well. The present sample is compared to one or more of these stored, past samples so that, based on a similarity between the present sample to the past samples, a generator fault indicated by the present sample can be identified. Identifying the generator fault can include recognizing that it is presently occurring or that it may occur in a predictable timeframe. Additionally, identifying a component of the generator that caused, or will cause, the generator fault can be identified as well. A diagnostic message or control signal based on the identified generator fault can then be generated.

摘要： A conformable layer (14) for inhibiting electrical discharge between vent tubes (16) and strands (12) in an inner-cooled coil (5). The conformable layer comprises a resistive inner core (24) and a conductive strip (20) wrapped in a conductive outer wrap (26). The conductive strip (20) is electrically connected to the strands (12) at one end of the coil (5) and left to electrically float at the other end. In this configuration, the conformable layer (14) reduces voltage buildup between the vent tubes (16) and the strands (12) to help prevent electrical damage to the coil (5).

摘要： A blown fuse proximity sensing device 40 is for use with a rectifying wheel 37 of a type including rectifying diodes 38 and associated fuses 42. Each fuse 42 may include a housing 51, a fuse element 52 carried by the housing, and a pop-out indicator 54 movable between a normal position and a popped-out position. In the popped-out position, the indicator 54 extends outwardly from the housing responsive to failure of the fuse element. At least one stationary proximity sensor 44 is mounted adjacent the rectifying wheel 37 for sensing positions of the pop-out indicators 54 without contact therewith during rotation of the rectifying wheel to thereby sense at least one blown fuse. The sensing device 40 may also include a local display 61, and a controller 68 connected to the stationary proximity sensor 44 for generating an indication of a blown fuse on the local display. The controller 68 may also generate at least one remote output, such as to be monitored by other plant control equipment.
