Iris Power RFAII-S

Periodic Online Rotor Magnetic Flux Analyzer
 

The RFAII-S is portable instrument to collect and analyze flux data from any flux probe in real time, providing the user with data on rotor winding shorted turns.

Features

Data Acquisition

  • Ideally used with permanently installed Iris Power Total Flux Probe (TFProbe) or Folding Flux Probe (FFProbe)
  • Inputs for shaft sync sensor (Keyphasor) for pole determination when shorts are detected.
  • Custom built, ultra-high resolution digital data acquisition module, including on-board switchable attenuation for maximum resolution  measurements using virtually any flux probe
  • High speed acquisition capability creates a table of results covering each pole and each load point

Data Analysis

  • The RFAII and RotorFluxPro software provides instant analysis to indicate the presence and location any rotor poles with shorted turns .

  • Analyzing the voltage waveforms in real time, comparing average and discrete flux readings, and trending readings to identify anomalies in the flux due to shorted turns.

Communication

  • Rugged portable instrument connects to a control computer using USB and Ethernet interfaces

Group Created with Sketch. Applications

  • The most common method of monitoring flux involves using a portable instrument, the Iris Power RFAII-S, which is moved between machines that are  fitted with flux probes. The instrument is configured by means of a computer and includes Windows™–based control and data display software.
  • Alternatively, for remote monitoring, continuous monitoring systems using FluxTracIITM are available from Qualitrol-Iris Power. These can be  integrated with plant SCADA using OPC protocol interface and a variety of other plant data acquisition and monitoring protocols.
