Elapsed time integrator TEIGGIO - -
11.10.2 Application
The function TEIGGIO 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.
11.10.3 Setting guidelines
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
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.
tOverflow is for overflow supervision with a default value tOverflow = 999 999.9
seconds. The outputs freeze if an overflow occurs.
