For details of the waveform data analysis, see Appendix B.
Note: If new disturbance record is stored in the relay while accessing the relay, the PC’s data may
differ from the relay’s. In this case, try to extract the data again.
The disturbance screen of GRB100 has another box for choosing DC at the bottom of AC ch. In
this selection, the RSM displays the waveform data every group of 32 signals since 128 binary
signals are divided to the 4 groups (1-32, 33-64, 65-96, 97-128). In the same manner of AC ch, the
waveform data can be shown by clicking the [Analysis] button after choosing DC from the
drop-down list box.
Alarm record
Some of the relays have “Alarm record” separate from the event record. Click the [Alarm record]
tab, then the [Alarm record] screen will appear on the top of the record screens.
The alarm records are displayed in order of new to old.
