The Iris Power RFAII-R technology is a second generation rotor flux analyzer that revolutionizes the analysis of the flux data by providing an initial diagnosis of the rotor winding condition usually even if the generator load is constant! This portable instrument can collect and analyze flux data from any flux probe in real time, providing the user with data on potential shorted turns. The Iris Power RFAII-R’s high-speed acquisition, high resolution capability and totally new analysis algorithms allow it to collect and analyze data over an entire unit run-down or start-up (with the shaft sync signal connected). Once configured, the Iris Power RFAII-R requires no user intervention and is ideal for profiling the rotor insulation condition before a machine outage or after a refurbishment.

• mechanical wear, especially that caused by frequent start/stop cycles
• distortion, breakage and migration due to centrifugal mechanical loading and thermally induced expansion/ contraction during load cycles
• overheating due to overloading/over excitation or inadequate or diminished cooling
• local overheating at high resistance brazed joints and at shorted turns
• contamination in cooling gas or copper dusting resulting in surface tracking between turns or to ground
• overvoltages induced from system events or from firing circuits in static exciters.
