Figure 13. TFR data subtab of the web interface.
TFR data is saved in the same basic format as for IPC401x. Data can thus be displayed by the same tool, see
[3]. For conversion to COMTRADE there is a special tool, available on Protrol's web page. Also, files from
IPC401x can be converted.
Figure 14. The log file with TFR data – phase currents and State.
At the end of the log file there is additional information to obtain traceability during error analysis. Here
can be found, among other things, version number, detector type, station name and scaling information.
See Figure 15.
Some of the information is necessary for the conversion to COMTRADE to work. This applies to frequency,
sampling frequency, CT ratio, resolution (RatedBinary) and time stamp.
