13.11 Elapsed time integrator with limit transgression andoverflow supervision TEIGAPC13.11.1 IdentificationFunction Description IEC 61850identificationIEC 60617identificationANSI/IEEE C37.2 devicenumberElapsed time integrator TEIGAPC - -13.11.2 ApplicationThe function TEIGAPC is used for user-defined logics and it can also be used for differentpurposes internally in the IED. An application example is the integration of elapsed timeduring the measurement of neutral point voltage or neutral current at earth-faultconditions.Settable time limits for warning and alarm are provided. The time limit for overflowindication is fixed to 999999.9 seconds.13.11.3 Setting guidelinesThe settings tAlarm and tWarning are user settable limits defined in seconds. Theachievable 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 range1.00 second ≤ tAlarm ≤ 99 999.99 seconds1.00 second ≤ tWarning ≤ 99 999.99 seconds.If the values are above this range the resolution becomes lower99 999.99 seconds ≤ tAlarm ≤ 999 999.9 seconds99 999.99 seconds≤ tWarning ≤ 999 999.9 secondsNote that tAlarm and tWarning are independent settings, that is, there is nocheck if tAlarm > tWarning.The limit for the overflow supervision is fixed at 999999.9 seconds.1MRK 505 337-UUS - Section 13Logic395Application manual
