Harmonic Components. The fundamental h01 and harmonics h02 h50 are represented by
the bin of the harmonic frequency.
The interharmonics ih01 ih50 are calculated from all spectral components between two
consecutive harmonic frequencies.
Examples:
On a 60 Hz system, the h02 at 120 Hz is represented by the bin no. 24 (120 Hz / 5 Hz = 24).
The harmonic h03 at 180 Hz is represented by the bin no. 36 (180 Hz / 5 Hz = 36).
The interharmonic ih02 is represented by the bins no. 25 to 35 (125 Hz to 175 Hz).
Select Harmonic Components for measurements according to standards, such as IEEE 519,
that require the harmonics components measurement according to IEC 61000-4-7 or
IEC 61000-3-12.
Sub-Grouped Harmonics. The fundamental h01 and harmonics h02 … h50 are the RMS
average of the bin of the harmonic frequency and one adjacent bin to each side.
The interharmonics ih01 … ih50 are composed of the remaining seven bins for 50 Hz systems
or nine bins for 60 Hz systems between two adjacent harmonics.
Examples:
On a 60 Hz system, the h02 at 120 Hz is represented by the bin no. 23, 24, and 25
(120 Hz / 5 Hz = 24).
The harmonic h03 at 180 Hz is represented by the bin no. 35, 36, and 37
(180 Hz / 5 Hz = 36).
The interharmonic ih02 is represented by the bins no. 26 – 34 (130 Hz…175 Hz).
Grouped Harmonics. The fundamental h01 and harmonics h02…h50 are the RMS average of
the bin of the harmonic frequency and half of the bins between two adjacent harmonic
frequencies to both sides. The center bin between two harmonic frequencies is included in
both harmonics with 50 %. Bins between h01 and h02 are not included.
Interharmonics are not available when the selection is grouped harmonics.
Examples:
On a 60 Hz system, the harmonic h03 at 180 Hz is represented by the bins 31-35, 36, 37-41,
50 % of bin no. 30 and 50 % of bin no. 42
The harmonic h04 at 240 Hz is represented by the bin no. 43-47, 48, 49-53, 50 % of bin no.
42 and 50 % of bin no. 54
The advantage of the measurements using grouped harmonics is to cover the entire spectrum
without the need to store memory-consuming interharmonics. Make sure to apply this
measurement only if the applicable standard requires this measurement method.
