ABB REB670 - Comparator for Real Inputs - REALCOMP; Application; Identification; Setting Guidelines

Set the EnaAbs = Absolute
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

13.14.2 Application
GUID-5F7B1683-9799-4D27-B333-B184F8861A5B v1
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 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.
