Event Reporting
Differential Event
Report (EVE DIFz
Command)
The differential event report includes:
➤ Differential analog quantities for 87-1, 87-2 and 87-3 differential
elements
➤ Digital states of differential and harmonic protection elements,
plus status of base model digital inputs and outputs
➤ Event summary
➤ Relay settings
Use the EVE DIFz n command to view the normal Differential Report (z =1
for 87-1 element, z = 2 for 87-2 element and z = 3 for 87-3 element) with
4 samples/cycle for report n (if not listed, n is assumed to be 1).
Refer to the example event report in Figure 9.7 to view the differential event
report columns. This example event report displays rows of information each
1/4 cycle. Retrieve this report with the EVE DIF1 command.
Table 9.4 gives the Differential event report column definitions for the Analog
Quantities IOPz, IRTz, IzF2 and IzF5 for z = 1, 2 and 3. Table 9.5 gives the
Differential event report digital column definitions for the Protection and
Control elements and the base model inputs and outputs.
