RFAII-R Periodic Online Rotor Magnetic Flux Analyzer
Brand: IRIS PowerThe 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
