Data Sheet

5
Continuous data calculation processing of all data without fail! Time series fluctuation results are displayed in the TIME PLOT screen
■ All measurement results are automatically recorded
-1. RMS fluctuation (dual screen display selection)
-2. Voltage fluctuation (interval and event displays)
-3. Harmonic fluctuation (harmonics and inter-harmonics displays)
-4. Flicker (graph and list displays)
• Pst and Plt measurement conditions according to IEC standards
•
ΔV10 measurement (according to Japanese domestic guidelines)
I n addition to displaying the various measurements in fluctuation graphs, the 3196 also displays the maximum,
minimum, and average values for each specified interval.
Further, when the 3196 captures a power anomaly, an event marker appears in the upper part of the graph.
Simply set the interval and start time series measurement to display events in the fluctuation graph
RMS fluctuation, voltage fluctuation, harmonic fluctuation, and flicker (IEC and ∆V10) time series data is
displayed on the TIME PLOT screen. In addition to cursor measurement, you can enlarge events that occur in
the voltage fluctuation event screen if a voltage dip, swell, or instantaneous interruption event occurs during
the measurement period.

■ Calculation method for measured data
- 1. RMS fluctuations/Harmonic fluctuations : Values are calculated continuously
every 200 ms.
The maximum, minimum, and average values are those applicable within the
specified interval.
-2. Voltage fluctuations : Values are calculated for a single waveform shifted by a half wave.
The maximum and minimum values are those applicable within the specified interval. Detailed
measurement of voltage fluctuations is possible because values are calculated every half wave.
-3. Flicker : Values are calculated in accordance using calculation methods defined in the
IEC and ∆V10 standards.

Cursor values (maximum, minimum, and average values for the specified
interval) are displayed.
Cursor values (maximum and minimum values for the specified interval) are
displayed.
Event display
When an event such as a
dip, swell, or instantaneous
interruption occurs, the time axis
is enlarged on the event screen.
When a power anomaly occurs during measurement, the event is indicated
using the ▼ marker.

You can specify display of up to six harmonic orders.
Cursor values are
displayed for the
specified orders.
Displays the Pst and Plt values as a graph once every ten minutes.
Displays a list of detailed data for Pst and
Plt values once every ten minutes.

Even when a long
interval is set,
momentary voltage
fluctuations are
accurately captured.
