15.6 Flicker Reference Impedance
Flicker measurements require the use of a reference impedance according to IEC 725. Since this
reference impedance has to be matched to the output of the AC source used, the PACS-1 is
available in different versions to accommodate the different AC sources that may be part of the
CTS system. The following reference impedances are available:
Model Phases Flicker Impedance
PACS-1RP 1 For RP Series based CTS system. Single phase
lumped impedance built into PACS-1 cabinet.
PACS-1 1 For 3001iX-CTS and 5001iX-CTS using programmable
impedance. (Standard)
Option -LR1 1 For 3001iX-CTS and 5001iX-CTS using optional
lumped impedance. (Single phase lumped impedance
built into PACS-1 cabinet.)
PACS-3 3 For 15003iX-CTS using programmable impedance.
(Standard)
Option -LR3 3 For 15003iX-CTS using optional lumped impedance.
(Three phase lumped impedance provides through
OMNI-3-18i cabinet.)
Option -LR4 3 For 30003iX-CTS using lumped impedance. (Three-
phase lumped impedance provides through OMNI-3-
37i cabinet.)
Option -LR5 3 For single phase testing of EUT's at 100 V L-N for the
Japanse flicker test standard, an OMNI-1-37iJ is
available as option -LR5.
