Waveform Data Analysis
1 Q. When displaying the waveform without voltage, messages of "No 3-phase voltages." and "No voltage
drops." are shown.
A. In default, the fault information is calculated automatically as "Measurement Result of Fault Section"
when data is opened. The above messages are shown in the case of no voltage. So click [Set] on menu
bar, click [Option] in the drop-down menu, and remove the checkmark of "Fault Section
Calculation" in the dialog box. And then the messages aren't shown from the next starting.
2 Q. In spite of inputting current by three-phase equilibrium, all is the same phase in Vector diagram.
A. In Vector diagram, the default setting of phase reference angle is "Phase A Voltage" even though the
model without voltage. So change the phase reference angle "Phase A Voltage" into a current. Click
[Set] on menu bar, click [Reference phase] in the drop-down menu, and select the desired channel
and current in the "Channel" and "Phase order" drop-down list boxes.
3 Q. When displaying the RMS value in the GRB100 relay, only certain channel's voltage or current
information is shown.
A. If other channel's voltage or current information will be shown, click [Set] on menu bar, click [Phase
rotation] in the drop-down menu, and select any channel's voltage or current in the drop-down list
box.
4 Q. The phase angle display is "---" in RMS value.
A. The default setting of phase reference angle is "Phase A Voltage" even though the model without
voltage. So change the phase reference angle into a current. Click [Set] on menu bar, click [Reference
phase] in the drop-down menu, and select the desired channel and current in the "Channel" and
"Phase order" drop-down list boxes.
5 Q. The upper half of RMS value is all "---".
A. The upper half of the screen for RMS value displays voltage information and the lower half of that
current information. Therefore the upper half is shown as "---" in the case of the model without
voltage and the lower half is "---" in the case of the model without current.
6 Q. In Symmetrical Component, the positive, the negative and the zero sequence components are
displayed, it isn't clear what voltage or current has these components.
A. This function displays the positive, the negative and the zero sequence components of the voltage or
current selected by [Set] menu. So, click [Set] on menu bar, click [Phase rotation] in the drop-down
menu, and read the selected voltage or current.
7 Q. It is hard to see the waveform of Binary data for its yellow color.
A. Change the color as follows: Click [File] on menu bar, click [Properties] in the drop-down menu,
click [Elements] button in the dialog box, click [Binary Elements(CH select)], select the data, click
[Edit] button, and select the Ch number (data) and desired color in the drop-down list boxes.
8 Q. When viewing the recorded waveform, it takes long time to designate the file by starting RSM100.
A. By running "hakei.exe" as an executable file in the installed folder and opening the waveform file
(extension OSC), it is not necessary to start RSM100 for displaying the waveform. And it is more
convenient that the files with extension OSC run "hakei.exe" directly by the folder option of
Explorer.
9 Q. The waveform displayed by disturbance record would like to be stored as COMTRADE file type.
A. Designate the file name and the place to store by clicking [Analysis] on menu bar and [Save As
ComTrade File Type] in the drop-down menu.
