INFOBEREICH
Die Angabe „MatNr/Version/Datum“ bzw. „1234560000/00/MM.YY“ ist als Textvariable deniert
und kann nur auf der „Rueckseite“ editiert werden. Die Textvariable erscheint in allen Doku-
menten dieses Buches, sobald eine Synchronisierung des gesamten Buches(!) durchgeführt
wird. ACHTUNG Die „Rueckseite” muss als Formatquelle(!) ausgewählt sein!
- Manual - the transient monitoring uses the set threshold values.
• Fast increase: If the difference between two neighbouring sampled points exceeds the set threshold, a
transient is recognised.
- Available settings:
- Off - transient monitoring has been switched off.
- Automatic - the threshold value is calculated automatically and comes to 0.2175 times the current
200 ms effective value.
- Manual - the transient monitoring uses the set threshold values.
• If a transient has been recognised, the threshold value increases by 20 V, both in automatic and in manu-
al mode. This automatic increase of the threshold value switches off within 10 minutes.
• If a transient has been recognised, the wave form will be saved to a transient record.
• If a further transient is recognised within the next 60 seconds, it will be recorded with 512 points.
4.3.5.9 Transient recording
• If a transient has occurred, the wave shape can be saved in a transient record with an adjustable number
of sampled points before and after the transient.
• Thetimebetweentwosamplepointsisalways50μs.
• You can choose between the following measurement channels for recording in the transient record:
• The phase voltage will be recorded with the transient.
• The phase voltage and current will be recorded with the transient.
• All currents will be recorded.
• All voltages and all currents will be recorded.
Record length
• The number of sample points to be saved before the transient occurred:
- Pre-runsettingrange:64...8192points(uptormwarerel.1.1:64..6144points)
- After-runsettingrange:64...8192points(uptormwarerel.1.1:64..6144points)
4.3.5.10 Averaging intervals
• Parameterisationoftheoatingaverage(previousnamefortrailingvalueindicator)fortheindividual
measurement values.
• The measurement values of the mean values are marked in the device display with an overline.
• The values can also be used for operators or comparators (Jasic).
• The adjustment range of the reporting times of the selected group (L1-L4) is 10, 15, 30, 60 seconds and
5, 8, 10, 15 minutes.
• The settings of different reporting intervals for each individual phase are made on the device.
