Chapter 13 Specifications
Harmonic voltage and harmonic current (including fundamental component) (Uharm/Iharm)
Measurement method Uses IEC61000-4-7:2002.
Max. order: 50th
Anti-aliasing low-pass filter causes attenuation of frequencies other than measurement target of at
least 50 dB.
Indicated harmonic voltage and harmonic current values incorporate inter-harmonics components
adjacent to the next whole-number harmonic component after harmonic analysis. (For details see
"13.10 Calculation Formula" (p.198).)
Measurement accuracy is specified for input that is 10% to 200% of IEC61000-2-4 Class 3.
Analysis window width 10 cycles (50 Hz), 12 cycles (60 Hz), or 80 cycles (400 Hz)
No. of window points Rectangular, 4,096 points
Displayed item From order 0 to 50 (with a fundamental wave of 40 to 70 Hz)
From order 0 to 10 (with a fundamental wave of 360 to 440 Hz)
Select either RMS or content percentage (When using content percentage, zero suppression
causes all orders to be given as 0% when the RMS value is 0.)
Measurement range, resolution Harmonic voltage: 600.00 V
Harmonic current: Varies with current range (see input specifications).
Measurement accuracy See measurement accuracy with a fundamental wave of 50/60 Hz and measurement accuracy
with a fundamental wave of 400 Hz.
Event threshold Harmonic voltage: 0.00 to 780.00 V (order 0: absolute value comparison)
Harmonic current: Varies with clamp sensor ×1.3 (see input specifications) (order 0: absolute val-
ue comparison).
Event IN Start of approx. 200 ms aggregation in which readings were greater than the threshold for each order
Event OUT Start of approx. 200 ms aggregation in which readings were less than (threshold - hysteresis) for each order
Multiple-phase system treatment Separate by channel
Saved waveforms Event waveforms
Constraints When using an AC-only clamp sensor, order 0 is not specified for current and power.
Harmonic power (including fundamental component) (Pharm)
Measurement method Uses IEC61000-4-7:2002.
Max. order: 50th
Anti-aliasing low-pass filter causes attenuation of frequencies other than measurement target of at
least 50 dB.
Indicates harmonic power values consisting of harmonic power for each channel and the sum of
multiple channels. (For details see "13.10 Calculation Formula" (p.198).)
Analysis window width 10 cycles (50 Hz), 12 cycles (60 Hz), or 80 cycles (400 Hz)
No. of window points Rectangular, 4,096 points
Displayed item From order 0 to 50 (with a fundamental wave of 40 to 70 Hz)
From order 0 to 10 (with a fundamental wave of 360 to 440 Hz)
Select either RMS or content percentage (When using content percentage, zero suppression
causes all orders to be given as 0% when the RMS value is 0.)
Measurement range, resolution See power ranges.
Measurement accuracy See measurement accuracy with a fundamental wave of 50/60 Hz and measurement accuracy
with a fundamental wave of 400 Hz.
Event threshold 0 to (varies with range) (specified as absolute value)
Event IN Start of approx. 200 ms aggregation in which the reading is greater than the threshold (when the
threshold is positive) or less than the threshold (when the threshold is negative)
Event OUT Start of the approx. 200 ms aggregation in which the reading is less than (threshold - hysteresis)
(when the threshold is positive) or greater than (threshold + hysteresis) (when the threshold is neg-
ative) in the EVENT IN state
Multiple-phase system treatment Separate by channel
Saved waveforms Event waveforms
Constraints When using an AC-only clamp sensor, order 0 is not specified for current and power.
