Appendix
Voltage Waveform Comparison
Measurement method:
• A judgment area is automatically generated from the previous 200 ms aggregation waveform, and events are gener-
ated based on a comparison with the judgment waveform.
• Waveform comparison is performed at once for the entire 200 ms aggregation. Thresholds are applied as a percent-
age of the nominal input voltage RMS value.
Event IN and OUT:
Event IN : First time at which waveform diverges from judgment area
Event OUT : None
