Measurement of Swell/ Dip/ INT/ Inrush current

Each event will be detected with the r.m.s. values in one gapless waveform and with a half-wave over-
lapping. The beginning of the waveform where the first event is detected is regarded as the start of the
event. If further events are not detected in the following waveform, the beginning of the waveform is
regarded as the end of the event. The detected event is assumed to be continued between the start to
the end of event detection.

Example of Dip detection

* INT is detected in the same method.


Example of Swell detection

* Inrush current is detected in the same method.
