RFAII-R Periodic Online Rotor Magnetic Flux Analyzer

Brand: IRIS Power

The RFAII-R is portable instrument to collect and analyze magnetic flux data from any flux probe in real time, providing the user with data on rotor winding shorted turns.
Features
  • Rugged portable instrument with USB and Ethernet computer interfaces
  • Custom built, ultra-high resolution digital data acquisition and on-board switchable attenuation for maximum resolution measurements using any manufacturer’s flux probe
  • High speed acquisition with deep memory for complete and accurate data collection
  • Capable of storing over one hundred and fifty flux waveforms
  • Can be synchronized to a power frequency signal, or ideally to an external shaft sync signal (key phasor)
  • Use with 2-pole or 4-pole rotors
  • Predictions of turn-shorts in any slot, often regardless of the generator load point during data acquisition
  • A high-speed acquisition mode immediately creates a table of results covering each coil at each load point, including flux waveforms
  • Stand-alone mode where the Iris Power RFAII-R can collect data automatically as the generator goes through normal load changes
  • User friendly Windows™ based software for data display, analysis, and trending
  • Analysis software capable of reading and analyzing data files from other manufacturers’ portable instruments
  • Instant analysis of round rotor winding condition usually at any operating load
  • Where needed, ability to analyze tests at different loads for a more certain prediction of rotor winding condition
  • Able to perform a spot measurement, or automatically acquire results over days during normal generator load changes, without operator intervention
  • Works with conventional wedge-mounted flux probe, or the stator tooth-mounted Iris Power TFProbe™, which can often be retrofitted with the rotor in-place
  • Systems are available for remote and continuous monitoring
  • Optional mode for finding shorts in spin pits with the rotor operating at different speeds
  • Optional instrument that can be used with both round rotors and salient pole rotors
