Event D (Digital Event Report)
The digital event report contains the status of the overcurrent elements (instantaneous, definite-
time and inverse-time overcurrent phase, single-phase, calculated residual, and negative-
sequence overcurrent elements), combined current overcurrent elements, voltage and frequency
elements, dc battery monitor, and the demand current thresholds (phase, calculated residual, and
negative-sequence for each of the three winding inputs). The status of the Relay Word bits
TRIPn (n = 1, 2, 3, and 4), as well as the status of the eight digital outputs and six optoisolated
inputs, is also included.
Use the
EVE D
command to retrieve digital event reports. There are several options for
customizing the report format. The general command format is:
EVE D [n, Sx, Ly[-[w]]]
(parameters in [ ] are optional)
where:
n
Event number; defaults to 1 if not listed, where 1 is the most recent event.
Sx
Display x samples per cycle (4 or 8); defaults to 4 if not listed.
Ly
Display y cycles of data (1 to LER); defaults to LER if not listed.
Ly-
Display from cycle y to end of report.
Ly-w
Display from cycle y to cycle w.
Refer to Figure 9.3 for an example digital event report. This example event report displays rows
of information each quarter-cycle; it was retrieved with the
EVE D<ENTER>
command.
