QUALITROL-IRIS POWER IS THE WORLD’S LARGEST PROVIDER OF MONITORING AND TESTING EQUIPMENT FOR MOTOR AND GENERATOR WINDINGS Iris Power RFAII TM Periodic On-line Rotor Flux Analyzer A second generation advanced tool to find rotor winding shorted turns, during service, in round rotor motors and turbo generators and in salient pole motors and hydro generators The portable Iris Power RFAII analyzer is intended for on-line detection of shorted rotor turns on salient pole rotors (Iris Power RFAII-S) and round rotors (Iris Power RFAII-R). In addition to manual measurements, the Iris Power RFAII analyzer is capable of stand-alone data acquisition once it is configured, i.e. without a connected computer, and the collected measurements are saved in its internal memory. The analyzer is compact, simple to use, and user-friendly, while maintaining high resolutions and powerful algorithms.
