Specified for RMS voltage Urms and RMS current Irms. Current and power values incorporate current sensor accuracy.
-6. Flag concept
IEC61000-4-30 Flagging concept
If an unreliable values are produce during a dip, swell, or interruption, approx. 200-ms aggregation will be
“flagged.”
An interval data including the flagged 200-ms aggregation will also be flagged.
Flagged data are referenced to decide the frequency for an interruption, and are recorded in status informa-
tion of the TIME PLOT data. If events of a dip, swell, or interruption are set to off, the values are also flagged.
(37) Mains signaling voltage Msv, Msv%
Measurement method Compliant with IEC61000-4-30
Levels (Msv) or content rates compared to the nominal voltage (Msv%) are calculated based on
the mid-harmonic bin of 10/12-cycle RMS values of up to two set signal frequencies or four mid-
harmonic bins that most closely approximate those frequencies to display.
Displayed item Msv1, Msv%1, Msv2, Msv%2, the worst value between event IN and event OUT
Measurement range 600.00 V
Measurement accuracy Within the range of 3% to 15% of nominal voltage: ±5% rdg.
Within the range of 1% to 3% of nominal voltage: ±0.15% of nominal voltage
Event threshold Percentage of the nominal voltage
Event IN Start time of approx. 200 ms aggregation in which the Msv value exceeds the threshold value
Event OUT Depends on the set timeout.
Multiple-phase system treatment Starts when any one of the channels from U1 to U3 exceeds the threshold value.
Saved waveforms Available
Constraints Not displayed for 400 Hz measurement.
