Events
Events are threshold value violations of set
threshold values for current and voltage.
Here, threshold values are compared with the half
wave effective values for current and voltage from
the measurement channels. The event record con-
sists of a mean value, a minimum or maximum va-
lue, a start time and an end time.
Fig. Shows the half wave effective values
for an event.

• Monitoring of the threshold values can be swit-
ched off (Off/Manual).
• Threshold values and hysteresis must be set as
a percentage of the nominal value.
• Threshold values can be set for excess voltage,
undervoltage, voltage interruption and overcur-
rent.
• If an event has occurred, the corresponding
measurement value is recorded with the set
pre-run and after-run periods (respectively
0..1000 half waves).
• Event records are configured with the GridVis
and displayed with the event browser.
