5 SETTINGS
• PMU 1 TIMED TRIGGER POSITION: This setting specifies the amount of pre-trigger data in percent of the entire
record.
• PMU1 PORT 1 PHS-1 to PMU1 PORT 1 PHS-14: These settings specify synchrophasors to be recorded from the
superset of all synchronized measurements as indicated in the following table. These settings allow for optimizing the
record size and content depending on a given application. Select "Off" to suppress recording of a given value.
VALUE DESCRIPTION
Va First voltage channel, either Va or Vab
Vb Second voltage channel, either Vb or Vbc
Vc Third voltage channel, either Vc or Vca
Vx Fourth voltage channel
Ia Phase A current, physical channel or summation as per the source settings
Ib Phase B current, physical channel or summation as per the source settings
Ic Phase C current, physical channel or summation as per the source settings
Ig Fourth current channel, physical or summation as per the source settings
V1 Positive-sequence voltage, referenced to Va
V2 Negative-sequence voltage, referenced to Va
V0 Zero-sequence voltage
I1 Positive-sequence current, referenced to Ia
I2 Negative-sequence current, referenced to Ia
I0 Zero-sequence current
• PMU 1 REC PHS-1 NM to PMU 1 REC PHS-14 NM: These settings allow for custom naming of the synchrophasor
channels. Sixteen-character ASCII strings are allowed as in the CHNAM field of the configuration frame. Typically
these names would be based on station, bus, or breaker names.
• PMU 1 REC A-CH-1 to PMU 1 REC A-CH-8: These settings specify analog data measured by the relay to be included
as a user-selectable analog channel of the record. Up to eight analog channels can be configured to record any Flex-
Analog value from the relay. Examples include active and reactive power, per phase or three-phase power, power fac-
tor, temperature via RTD inputs, and THD. The configured analogs are sampled concurrently with the synchrophasor
instant.
• PMU 1 REC A-CH-1 NM to PMU 1 REC A-CH-8 NM: These settings allow for custom naming of the analog channels.
Sixteen-character ASCII strings are allowed as in the CHNAM field of the configuration frame.
• PMU 1 REC D-CH-1 to PMU 1 REC D-CH-16: These settings specify any digital flag measured by the relay to be
included as a user-selectable digital channel in the record. Up to digital analog channels can be configured to record
any FlexLogic™ operand from the relay. The configured digital flags are sampled concurrently with the synchrophasor
instant.
• PMU 1 REC D-CH-1 NM to PMU 1 REC D-CH-16 NM: This setting allows custom naming of the digital channels. Six-
teen-character ASCII strings are allowed as in the CHNAM field of the configuration frame.
