13.12.2 Application
GUID-B4B47167-C8DE-4496-AEF1-5F0FD1768A87 v2
The function TEIGAPC is used for user-defined logics and it can also be used for different
purposes internally in the IED. An application example is the integration of elapsed time during
the measurement of neutral point voltage or neutral current at earth-fault conditions.
Settable time limits for warning and alarm are provided. The time limit for overflow indication
is fixed to 999999.9 seconds.
13.12.3 Setting guidelines
GUID-2911D624-87D5-4427-BB2F-E0D1072394FA v3
The settings
tAlarm and tWarning are user settable limits defined in seconds. The achievable
resolution of the settings depends on the level of the values defined.
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 due to the 32 bit float
representation
99 999.99 seconds < tAlarm ≤ 999 999.0 seconds
99 999.99 seconds < tWarning ≤ 999 999.0 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.

13.13.2 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.
13.13.3 Setting guidelines
GUID-ADA3E806-BEF1-4D15-B270-207386A0AEE4 v2
For proper operation of comparison the set value should be set within the range of ± 2 ×10
