GE Multilin L90 Line Current Differential System 5-1155 SETTINGS 5.4 SYSTEM SETUP5k) PMU RECORDINGPATH: SETTINGS SYSTEM SETUP PHASOR MEASUREMENT PHASOR MEASUREMENT UNIT1 RECORDING PMU1• PMU 1 FUNCTION: This setting enables or disables the recorder for PMU 1. The rate is fixed at the reporting rate setwithin 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 ofrecords. As the number of records is increased the available storage for each record is reduced. The relay supports amaximum 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 memorystorage. Under the “Automatic Overwrite”, the last record is erased to facilitate new recording, when triggered. Underthe “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 entirerecord. This setting applies only to the timed mode of recording.l) AGGREGATORSPATH: SETTINGS SYSTEM SETUP PHASOR MEASUREMENT UNIT PMU AGGREGATOR 1When the protocol selection is set via the software or keypad, all aggregators whose protocol is not set to None willbe set to the last protocol saved (i.e., C37.118 or IEC61850-90-5) to any aggregators, as both C37.118 andIEC61850-90-5 simultaineous streaming of both R-SV values is not possible.
