4.4 Setting Event Detection [REC&EVENT]
67
4
With this instrument, an "event" is the detection of an anomaly (abnor-
mal phenomena) that may occur on power lines.
The detection criteria (Event Settings) are specified before recording
measurements.
When the specified criteria are satisfied while recording, the data is
recorded as an event, and can be analyzed on the EVENT screen.
Event settings are made on the SYSTEM-[REC&EVENT] screen.
This instrument supports eight types of events
See: Refer to: Event Details, "Detection Methods and Recording Contents of Events" (p. 110)
Event Recording
• Event criteria can be ORed together (logical sum).
• Events are recorded when recording starts and stops, regardless of
cr
iteria settings.
• The instrument can record data from up to 50 events (in the Event List
and Event Waveforms).
• Depending on the type of event, two recordings may occur: once when
a threshold is exceeded [IN
] and again upon return [OUT].
4.4 Setting Event Detection [REC&EVENT]
Parameter that can be analyzed on the EVENT screen:
• View event occurrences on the Event Monitor.
• View sequence, date, time and event parameter.
• View the voltage or current event waveform.
• On the detailed fluctuation graph, view rms fluctuations when an
event occurs.
