15.13 Comparator for integer inputs - INTCOMP
15.13.1 Identification
Function description
Comparison of integer values
15.13.2 Application
The function gives the possibility to monitor the level of integer 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.
15.13.3 Setting guidelines
For proper operation of comparison the set value should be set within the range of ± 2 ×10
Setting procedure on the IED:
EnaAbs : This setting is used to select the comparison type between signed and absolute values.
Absolute : Comparison is performed on absolute values of input and reference values
•
Signed : Comparison is performed on signed values of input and reference values.
•
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
•
SetValue : This setting is used to set the reference value for comparison when setting RefSource is
selected as
15.13.4 Setting example
For absolute comparison between inputs:
EnaAbs = Absolute
Set the
RefSource = Input REF
Set the
Similarly for Signed comparison between inputs
EnaAbs = Signed
Set the
RefSource = Input REF
Set the
For absolute comparison between input and setting
EnaAbs = Absolute
Set the
