Disturbances
Navigation: “Events” – “Definition” – “Disturbances.”
These events are similar to Transients. Instead of waveforms the half-period values for voltage,
current, phase angle, power, power factor, etc. are stored. Each Disturbance event will also
trigger an Transient event. In that way any kind of disturbance can be detected.

Navigation: “Events” – “List”
This panel shows a list of already captured events. It displays up to the last 1000 events - no
matter if they were stored or not. Event list is scrolled automatically or can be scrolled manually.
The Event table can be sorted by event time, type or phase. The list can be cleared and
disturbances or transients can be generated manually.
