VSM DESIGN

Class [009]
Apparatus comprised of electronic and software components for monitoring the dynamic air gap in hydro-electric generators, as well as other large rotating machines and also for monitoring the height, alignment and lateral position of linear motors and the vehicles propelled by same. Apparatus comprised of electronic and software components for the monitoring of any data relating to the performance of large generators and other rotating machines without requiring the stoppage of same. Measuring and monitoring systems suited for the harsh environment inside turbogenerating machines, namely: monitors true vibration without electrical runout and other interference; measures end-winding vibration to assess bracing condition, or for any application in high voltage or explosive environments; Monitors on-line stator bar vibration to determine wedge tightness and winding insulation condition; Measures magnetic flux emanating from rotor poles of generators to detect and diagnose any magnetic field imbalances; Inhibits alarm feature during machine transitory operating conditions to prevent false alarms and unnecessary shutdowns; Detects rotor movement in order to display rotational speed, to notify when it reaches standstill during shutdown, and to warn of undesired movement during maintenance; Measures axial displacement of turbogenerator shaft; Miscellaneous applications of capacitive technology to measure displacement, proximity, position, or air gap. Measuring and monitoring systems for hydroelectric turbine-generator sets, namely: Monitors true vibration without electrical runout and other interference; Monitor on-line stator bar vibration to determine wedge tightness and winding insulation condition; Measures end-winding vibration to assess bracing condition, or for any application in high voltage or explosive environments; Measures magnetic flux emanating from rotor poles of generators to detect and diagnose any magnetic field imbalances; Thermal mapping of stator core, stator windings and rotor poles; Alerts of a breakage and identifies the defective shear pin in the wicket gate operating mechanism of hydrogenerators; Detects rotor movement in order to display rotational speed, to notify when it reaches standstill during shutdown, and to warn of undesired movement during maintenance; Tests the static tightness of every stator wedge with a robot tool.
