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.

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 SetValue .
