Events
Events are threshold value violations of set
threshold values for current and voltage.
Here, threshold values are compared with the
full wave effective values for current and volta-
ge from the measurement channels. The event
record consists of a mean value, a minimum or
maximum value, a start time and an end time.
• Monitoring of the threshold values can be
switched off (Off/Manual).
• Threshold values must be set as a percentage
of the nominal value.
• Threshold values can be set for excess volta-
ge, undervoltage and overcurrent.
• An event is triggered if in the course of the pre-
run period there is an uninterrupted threshold
value violation. An event is ended if there are
no threshold value violations in the course of
the after-run period.
• If an event has occurred, the corresponding
measurement value is recorded with the set
pre-run and after-run periods (respectively
0..1000 full waves).
• Event records are configured with the GridVis
and displayed with the event browser.
