Metering and Monitoring
Through-Fault Event Monitoring
Use the TFE A command to list all the stored through-fault events (not only
the last 20 events) since the monitor was last reset. To list a particular number
of through-fault events, enter the TFE n command (n = 1 to 500).
To clear event accumulated data, and all event records, use either the TFE C
(clear) or TFE R (reset) command. Both commands have the same result, so
you can use either of them. Note that when you change the ETHRFLT setting,
the relay also clears the data and records, i.e. it has the same effect as the
TFE C or TFE R command.
Use the TFE P command to preload or change the values of the through fault
event accumulated data, as shown in Figure 5.20. Enter these values in percent
for each phase, to a maximum value of 100.0 percent.
