Frequency drift
The supply frequency is checked. Sudden frequency changes of more than 1Hz of the
nominal supply voltage are detected.
A waveform is stored for this event. Default Value 100%
Vector jump
The 3 supply phases are checked. Jumps of the voltage angle of more than 30° are detected.
A waveform is stored for this event. Default Value 30%
Neutral overvoltage
The neutral voltage is checked. A voltage above 10% of the nominal supply voltage is
detected. Default Value 10%
Power on/off
The last power on and off times are logged.
Harmonic current
The 3 supply phases are checked. Total harmonic distortions of a current above 2% are
detected. A waveform is is stored for this event. Default Value 100%
Time change
Changes to the internal clock time are logged.
