13.13 Comparator for real inputs - REALCOMP
13.13.1 Identification
Function description
Comparator for real inputs
13.13.2 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.
13.13.3 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
