Limit profiles

With this option you can predefine a limit profile for the harmonics or the interharmonics. This profile can be displayed in the Spectrum view. In addition, the predefined limits are saved as additional information in order to facilitate a later analysis.

You can find out how to configure additional profiles in chapter Grid module.
Configuration

Input

Select the input signal.

Update time

If the spectrum is required in another update time than 200 ms, you can set here as a default which time interval should be used.

Harmonics values

Select whether to measure relative or absolute harmonics/interharmonics.

Enable phase calculation

The corresponding phases for the harmonic values are also calculated.

Interference factor

Different calculation types can be selected for an interference factor.

  • Type:

    TIF (acc. to IEEE Std. 519): Describes the effects of harmonic voltages or currents on communication systems near transmission lines.

    THFF: European version of the TIF defined by the CCITT (Comité Consultatif International Téléphonique et Télégraphique), now ITU-T, in 1978.

    Linear: General calculation formula with harmonic values without squaring.

    Square: General calculation formula with squared harmonics

    Psophometry up to 50th harmonic can be mapped using the type square and the normalization Hn.

    Since ibaPDA supports only one weighting factor per harmonic, the factors have to be multiplied first for psophometry and specified as total weighting factor per harmonic.

  • Normalization:

    Hn/H1: All harmonics are normalized to the value of the fundamental frequency, i.e. divided by this value. This corresponds to the relative values in ibaPDA, however without the factor 100 for percent.

    Hn/RMS: All harmonics are normalized to the RMS value, i.e. divided by the RMS value

    Hn: absolute value of the harmonics
Analog tab

The Spectrum submodule calculates the absolute or relative harmonics 1-50 and the absolute or relative interharmonics 1-50 for the selected input channel plus the fundamental frequency and the total harmonic distortion in the 200 ms measurement interval.

Name

The names are already preset. For unambiguous identification, they contain the input channel and the characteristic value. You can additionally assign two comments when clicking the  symbol in the Name field.
