Table 43: Available synchrophasor values
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 channel 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, referenced to Va
I1 Positive-sequence current, referenced to Ia
I2 Negative-sequence current, referenced to Ia
I0 Zero-sequence current
Rec PHS-1 Name, Rec PHS-2 Name, Rec PHS-3 Name,..., Rec PHS-14 Name
Range: 16 character ASCII string
Default: GE-UR+PMU-PHS1, GE-UR+PMU-PHS2, GE-UR+PMU-PHS3,..., GE-UR+PMU-PHS14
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.
Rec A-CH-1, Rec A-CH-2, Rec A-CH-3,..., Rec A-CH-14
Range: available FlexAnalog™ values
Default: OFF
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 FlexAnalog value from the relay. Examples include active and reactive
power, per phase or three-phase power, power factor, and THD. The configured analogs
are sampled concurrently with the synchrophasor instance.
Rec A-CH-1 Name, Rec A-CH-2 Name, Rec A-CH-3 Name,..., Rec A-CH-14 Name
Range: 16 character ASCII string
Default: AnalogChannel1, AnalogChannel2, AnalogChannel3,..., AnalogChannel14
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.
Rec D-CH-1, Rec D-CH-2, Rec D-CH-3,..., Rec D-CH-14
Range: any metering logic operand or shared operand
Default: OFF
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 operand from the relay. The configured digital flags are sampled
concurrently with the synchrophasor instance.
Rec D-CH-1 Name, Rec D-CH-2 Name, Rec D-CH-3 Name,..., Rec D-CH-14 Name
Range: 16 character ASCII string
Default: AnalogChannel1, AnalogChannel2, AnalogChannel3,..., AnalogChannel14
This setting allows custom naming of the digital channels. Sixteen-character ASCII
strings are allowed as in the CHNAM field of the configuration frame.
