Janitza AHF
51
Operating modes:
The AHF has three main functions:
• Harmonics compensation (H),
• Power factor correction (Q) and
• Compensation of imbalance (B).
The AHF offers 12 “Operating modes”:
• 0 H
• 1 H+Q
• 2 H+Q+B
• 3 internal use (auto-aging)
• 4 H+B+Q
• 5 H+B
• 6 Q+H
• 7 Q+H+B
• 8 Q+B+H
• 9 B+H
• 10 B+H+Q
• 11 B+Q+H
Various different combinations of functions with prioritization are possible:
Example combinations
• H+Q+B: Prioritized compensation of the harmonic, then power factor correction and
compensation of the imbalance.
H+Q+B: Prioritized compensation of the harmonic, then compensation of the imbalance
and reactive power;
• Mode 0 means sole compensation of the harmonic,
• Q+H means prioritized compensation of the reactive power and then harmonic compen-
sation.
• Press the “

” button (Figure 4-14), to go to the “Harmonic Comp.” menu.
• Set the desired compensation of even and odd harmonics current in %
(Figure 4-15, 4-16).

Operating mode: There are 12 operating
modes available, see below.
Start Mode: “Auto”: The AHF automatically
compensates the load harmonics current.
“Manual”: Compensation only begins once
the power on command has been received
(Power ON).
Transformer Position: Load or grid side
Total Current: Total current of the system
