ABB Relion REC670 - Comparator for Integer Inputs - INTCOMP; Identification; Application; Setting Guidelines

A resolution of 10 ms can be achieved when the settings are defined within the range
1.00 second ≤ tAlarm ≤ 99 999.99 seconds
1.00 second ≤ tWarning ≤ 99 999.99 seconds.
If the values are above this range the resolution becomes lower
99 999.99 seconds ≤ tAlarm ≤ 999 999.9 seconds
99 999.99 seconds≤ tWarning ≤ 999 999.9 seconds
Note that tAlarm and tWarning are independent settings, that is, there is no
check if tAlarm > tWarning .
The limit for the overflow supervision is fixed at 999999.9 seconds.

15.13.2 Application
GUID-4C6D730D-BB1C-45F1-A719-1267234BF1B9 v1
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
GUID-ADA3E806-BEF1-4D15-B270-207386A0AEE4 v1
For proper operation of comparison the set value should be set within the range of ± 2 ×10
9
.
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 .
