Voltage Events
Function Description
The device detects voltage events (dips, swells, interruptions) based on 1/2-cycle RMS values according to
IEC 61000-4-30 Edition 3.0.
The device works as follows:
•
It determines the start of events with the threshold value.
All thresholds are related to the primary nominal voltage.
•
It determines the end of voltage events with the voltage considering the hysteresis of the preset
threshold.
