5.4 SYSTEM SETUP
k) PMU RECORDING

PATH: SETTINGS SYSTEM SETUP
 PMU 1
 RECORDING
• PMU 1 FUNCTION: This setting enables or disables the recorder for PMU 1. The rate is fixed at the reporting rate set
within the aggregator (i.e., Aggregator 1).
• PMU 1 NO OF TIMED RECORDS: This setting specifies the number of timed records that are available for a given log-
ical PMU 1(4). The length of each record is equal to the available memory divided by the content size and number of
records. As the number of records is increased the available storage for each record is reduced. The relay supports a
maximum of 128 records in either timed or forced mode.
• PMU 1 TRIGGER MODE: This setting specifies what happens when the recorder uses its entire available memory
storage. Under the "Automatic Overwrite", the last record is erased to facilitate new recording, when triggered. Under
the "Protected" selection, the recorder stops creating new records when the entire memory is used up by the old un-
cleared records.

• PMU 1 TIMED TRIGGER POSITION: This setting specifies the amount of pre-trigger data as a percent of the entire
record. This setting applies only to the timed mode of recording.
l) AGGREGATORS

PATH: SETTINGS SYSTEM SETUP
 PMU AGGREGATOR 1

When the protocol selection is set via the software or keypad, all aggregators whose protocol is not set to None will
be set to the last protocol saved (i.e., C37.118 or IEC61850-90-5) to any aggregators, as both C37.118 and
IEC61850-90-5 simultaneous streaming of both R-SV values is not possible.
