We specialise in the design, manufacture and supply of Test Equipment for detecting and locating faults in the field windings of large
cylindrical turbo-alternator rotors.
Our main products are the **TDR200 Rotor RSO Relectometer**,the RFM 200 Rotor Magnetic
Flux Probe Monitor and the RWG100 Flux probe calibrator. The RSO test is carried out on generators which are isolated and off-load, while the Flux Probe test is performed
with the generator running and on-load. The RWG100 is a calibrator and precision waveform generator for use with flux probe analysis equipment, including
the Rowtest RFM100
** IMPORTANT NOTICE** Because of component supply problems, we are currently
unable to quote for or supply the TDR200 Rotor RSO Relectometer. We will update this web site
if or when the parts become available.
The TDR200 Rotor Reflectometer
The TDR200 Rotor Reflectometer,
uses the RSO (Recurrent Surge Oscilloscope) off-line test
method to detect faults in power turbogenerator
alternator rotor windings. It replaces our original TDR100
version, which displayed the test waveforms on
an analogue or digital oscilloscope and was previously
manufactured by our associate company, Convex Design Ltd.(CDL). For further details, please click
here.
The RFM200 Rotor Flux Probe Monitor
The RFM200 Rotor Flux Probe Monitor detects winding faults by processing the output signal from a magnetic flux probe (search coil)
located in the air gap between a rotor and its stator. It is an on-line test method which is used with the generator
in its normal operating mode. For further details, please click here.
The RWG Flux Probe Calbrator and waveform generator
The RWG100 is a calibrator and precision waveform generator for use with Rotor Flux Probe analysis equipment, including
the Rowtest RFM100. For further details, please click here.
