Identification

Function description
Comparator for real inputs
15.14.2

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.

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.
