UMG 508TransientsTransient voltages are rapid, impulsive transientoscillation processes in electrical networks.Transient voltages are not predictable with respectto time and last for a limited period.Transient voltages are caused by the effects oflighting, due to switching operations or the triggeringof fuses.• The UMG508 recognizes transients that arelonger than 50µs.• The UMG508 monitors the voltage measurementinputs on transients.• Transient monitoring can be set per phase.• There are two independent criteria for recognizingtransients.• If a transient has been recognized, the waveshape is saved in a transient recording.• If a transient has been recognized, the limitvalue is automatically increased by 20V, bothin automatic and manual modes. This automaticincrease of the limit value fades within10 minutes.• If another transient is recognized within thenext 60 seconds, this transient is recordedwith 512 points.• You can display recorded transients with theGridVis incident browser.54

UMG 508Mode (absolute)If a scanning value exceeds the set limit value, atransient is recognized.• Off- Transient monitoring is switched off• Automatic- Factory pre-setting. The limit valueis automatically calculated and is 110% ofthe current 200 ms effective value.• Manual- Transient monitoring uses the adjustablelimit value under "Peak U“.Mode (delta)If the difference of two neighbouring scanningpoints exceeds the set limit value, a transient isrecognized.• Off- Transient monitoring is switched off.• Automatic- Factoring pre-setting. The limitvalue is calculated automatically and is 0.2175times the current 200ms effective value.• Manual- Transient monitoring uses the adjustablelimit value under "Trns U“.Accept L2-L4Transient monitoring can be set per phase.

UMG 508EventsEvents are threshold value violations of setthreshold values for current and voltage.Here, threshold values are compared with thefull wave effective values for current and voltagefrom the measurement channels. The eventrecord consists of a mean value, a minimum ormaximum value, a start time and an end time.• Monitoring of the threshold values can beswitched off (Off/Manual).• Threshold values must be set as a percentageof the nominal value.• Threshold values can be set for excess voltage,undervoltage and overcurrent.• An event is triggered if in the course of the prerunperiod there is an uninterrupted thresholdvalue violation. An event is ended if there areno threshold value violations in the course ofthe after-run period.• If an event has occurred, the correspondingmeasurement value is recorded with the setpre-run and after-run periods (respectively0..1000 full waves).• Event records are configured with the GridVisand displayed with the event browser.Limit valueviolationsbefore thelead timeLead timeStart time event(Trigger time)Pre-runEvent recordAfter-runEventFollow-up timeMeasuredvalueVollwelleneffektivwertLimit valueEnd timeLimit value violationsbefore the follow-up timeFig. Shows the full wave effective values for anevent.56
