Function description
Comparator for real inputs
15.14.2
Application
The function gives the possibility to monitor the level of real values in the system relative to each
other or to a fixed value. It is a basic arithmetic function that can be used for monitoring,
supervision, interlocking and other logics.

Setting guidelines
Setting procedure on the IED:
EnaAbs : This setting is used to select the comparison type between signed and absolute values.
Absolute : The function will do absolute comparison between input and reference value.
•
Signed : The function will do signed comparison between input and reference value.
•
RefSource : This setting is used to select the reference source between input and setting for
comparison.
REF : The function will take reference value from input REF
•
•
SetValue : The function will take reference value from setting SetValue
SetValue : This setting is used to set the reference value for comparison when setting RefSource is
selected as
will never pickups.
RefPrefix : This setting is used to set the unit of the reference value for comparison when setting
RefSource is selected as SetValue . It has 5 unit selections and they are Milli, Unity, Kilo, Mega and
Giga.
EqualBandHigh : This setting is used to set the equal condition high band limit in % of reference
value. This high band limit will act as reset limit for INHIGH output when INHIGH is high in last
execution.
EqualBandLow : This setting is used to set the equal condition low band limit in % of reference
value. This low band limit will act as reset limit for INLOW output when INLOW is high in last
execution.
