13.12 Comparator for integer inputs - INTCOMP
13.12.1 Identification
Function description
Comparison of integer values
13.12.2 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.
13.12.3 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 : 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
13.12.4 Setting example
For absolute comparison between inputs:
EnaAbs = 1
Set the
RefSource = 1
Set the
Similarly for Signed comparison between inputs
EnaAbs = 0
