Issue 1.3
Basic settings
See Power frequency submodule, “General” tab, chapter 10.3.2
Configuration
Input
Select the input signal.
Update interval
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 cur-
rents on communication systems near transmission lines.
THFF:
European version of the TIF defined by the CCITT (Comité Consultatif In-
ternational Téléphonique et Télégraphique), now ITU-T, in 1978.
Important note
The total number of Harmonic voltage and Spectrum submodules per ibaPQU must
not exceed nine (9) to avoid overloading the system.
