lography trace depends in part on the number of parameters selected here. Parameters set to "Off" are ignored. The
parameters available in a given relay are dependent on: (a) the type of relay, (b) the type and number of CT/VT hardware
modules installed, and (c) the type and number of Analog Input hardware modules installed. Upon startup, the relay will
automatically prepare the parameter list. A list of all possible analog metering actual value parameters is presented in
Appendix A: FlexAnalog Parameters. The parameter index number shown in any of the tables is used to expedite the
selection of the parameter on the relay display. It can be quite time-consuming to scan through the list of parameters via the
relay keypad/display - entering this number via the relay keypad will cause the corresponding parameter to be displayed.
All eight CT/VT module channels are stored in the oscillography file. The CT/VT module channels are named as follows:
<slot_letter><terminal_number>—<I or V><phase A, B, or C, or 4th input>
The fourth current input in a bank is called IG, and the fourth voltage input in a bank is called VX. For example, F2-IB desig-
nates the IB signal on Terminal 2 of the CT/VT module in slot F. If there are no CT/VT modules and analog input modules,
no analog traces will appear in the file; only the digital traces will appear.
The source harmonic indices appear as oscillography analog channels numbered from 0 to 23. These correspond
directly to the to the 2nd to 25th harmonics in the relay as follows:
NOTE
Analog channel 0 ↔ 2nd harmonic
Analog channel 1 ↔ 3rd harmonic
...
Analog channel 23 ↔ 25th harmonic
