4-point characteristic curve
By selecting "4-point characteristic curve" it is possible to define a characteristic curve using four points.

Reductions
The following configuration options are available in the Reductions section.
•
Gradient limit (adjustment rate):
If the power company requires a reduction, it has to be configured in this box. (Enter the values in
seconds)
•
Max. cos(phi) inductive/under excited and max. cos(phi) capacitive/over-excited:
A maximum shift factor can be defined wit this the reduction. With this, it can be that less reactive
power is fed-in into the grid than what the characteristic curve allows in the partial load range in
order to maintain the shift factor limits.
