Threshold setting for Power quality (Event) KEW6315
- 65 - KEW6315
Threshold setting for Power quality (Event)
Press the (OFF/ ON) to disable or enable the “threshold value” entry. If “OFF” is selected, the
item will not be recorded even the threshold value is set for it. The threshold value used during the
previous measurement is displayed by pressing the (ON) key.
Caution:
Threshold values for “Swell”, “Dip” and “INT” are the percentage of the nominal voltage. So when the nominal
voltage is changed, threshold voltage will be altered accordingly. For “Transient”, if the nominal voltage is
changed, the initial value will be automatically set to “300%”, which is three times the new nominal voltage (peak
voltage). The threshold value for “Inrush current” is the percentage of the Current Range, therefore, the value will
be altered if the setting of the current range is changed.
”Hysteresis”
Set a desired hysteresis in percentage to disable the event detection for the specific area. Setting a proper
hysteresis will be helpful to prevent unnecessary detections of events which are caused by voltage or
current fluctuations around the threshold values.
Selection
1 - 10%against the nominal voltage (5%)
* Default value is highlighted in gray.
Move the blue highlight to “Hysteresis”. Show the value entry window.*
Set the hysteresis [%]. Confirm. Cancel.
* A pop-up appears and show the effective range.
