The TDR200 Rotor Reflectometer, uses theRSO (Recurrent Surge Oscilloscope) method to detect faults in turbogenerator alternator rotor windings. It replaces our original TDR100 version, which displayed the test waveforms on an oscilloscope and was previously manufactured by our associate company, Convex Design Ltd. (CDL). The TDR200 is similar to the original TDR100 model, but has an additional high-resolution digital interface, which displays the rotor waveforms directly on the screen of a laptop PC. Consequently, a portable oscilloscope and/or camera are no longer required to carry out the test. However, the TDR200 can be used with an oscilloscope if a PC is not available, in which case its operation is identical to that of the original TDR100 instrument.

method, please click here A large amount of technical information about the RSO test method, including manuals for the TDR200 Rotor Reflectometer can be found on our Support page ROTOR MAGNETIC FLUX PROBE MONITOR RFM200 Our new Rotor Flux Monitor (RFM200) detects rotor winding faults by analysing the output of magnetic flux probes (seach coils) installed in the air gaps of large electricity generators. This instrument analyses the flux probe signal in real-time and detects current-carrying winding faults. It is an updatedversion of the original RFM100< instrument which was previously supplied by Convex Design Ltd. For details of the RFM200 equipment, please click here.
