15.12 Elapsed time integrator with limit transgression and
overflow supervision TEIGAPC
15.12.1 Identification
Function Description
Elapsed time integrator
15.12.2 Application
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.
15.12.3 Setting guidelines
The settings
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
The limit for the overflow supervision is fixed at 999999.9 seconds.

TEIGAPC
tAlarm and tWarning are user settable limits defined in seconds. The achievable
tAlarm and tWarning are independent settings, that is, there is no check
Note that
tAlarm > tWarning .
