Stage power

The stage power is the
power of a capacitor
stage. In the standard
programming the stage
power can only be pro-
grammed for the first stage. In the expanded program-
ming you can set the stage power for each capacitor
stage. If you only enter the stage power for the first
capacitor stage, the other stages are fixed by the stage
ratio. The stage power of each capacitor stage can be
calculated from the first stage and the corresponding

stage ratio.

Ratio 0var - 9999kvar
Example 1
Power of the first capacitor stage = 10kvar
Stage ratio
All following stages have the power: 10kvar
Example 2
Power of the first capacitor stage = 20kvar
Stage ratio
The stages have the power:
1. Stage
2. Stage
3. Stage
4. Stage
5. Stage
etc.
Example: Programming stage power

Stage ratio
The stage ratio states
the ratio of the stage
power of the various
capacitor stages. The
power of the first ca-
pacitor stage serves as a reference. The stage ratio is
programmable for each stage up to the fifth stage.
Setting range : 0 - 9
In the display only the stage ratio for the capacitor
stages 2, 3, 4 and 5 are indicated. The stage ratio for
the first capacitor stage is always 1.
Example 1
The stage ratio is programmed to 1:2:4:8:8:8..., and in
the four digit-display, only the part "2:4:8:8" is indi-
cated.
1 . 2 . 4 . 8 . 8 . 8....
Indicated on display.
Example 2
The stage ratio is programmed to 1:2:0:2:2:2.... In the
4-digit display only the part "2:0:2:2" is indicated.
1 . 2 . 0 . 2 . 2 . 2....
Indicated on display.
If the first capacitor stage has a power of 10kvar, the
following stages have the power:
1. Stage
2. Stage
3. Stage
4. Stage
5. Stage
etc.
