Set the RefSource = Set Value
SetValue shall be set between -2000000000 to 2000000000
Similarly for signed comparison between input and setting
Set the EnaAbs = Signed
Set the RefSource = Set Value
SetValue shall be set between -2000000000 to 2000000000

Comparator for real inputs - REALCOMP

Identification

Function description
Comparator for real inputs

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: Comparison is performed with absolute values of input and
reference.
• Signed: Comparison is performed with signed values of input and reference.
RefSource: This setting is used to select the reference source between input and
setting for comparison.
• Input REF: The function will take reference value from input REF
• Set Value: The function will take reference value from setting SetValue
