Settings for Synchrophasors
FNR
Selects the numeric representation of the two frequency values in the synchro-
phasor data stream. If MFRMT = FM, this setting is forced to F, a floating point value.
NUMANA
Selects the number of user-definable analog values to be included in the synchro-
phasor data stream.
Setting NUMANA := 0 sends no user-definable analog values.
Setting NUMANA := 1–16 sends the user-definable analog values, as
listed in Table 18.5.
The format of the user-defined analog data is always floating point, and each
value occupies four bytes. If MFRMT = FM, this setting is forced to 0 and the
relay does not send any user-definable analog values.
NUMDSW
Selects the number of user-definable digital status words to be included in the
synchrophasor data stream.
Setting NUMDSW := 0 sends no user-definable binary status words.
Setting NUMDSW := 1, 2, 3, or 4 sends the user-definable binary status words,
as listed in Tab le 18.6 . If MFRMT = FM, this is forced to 1.
