To set line drop compensation correctly, you need to calculate the ohmic
and inductive voltage drop in V with reference to the secondary side of the
voltage transformer. You also need to correctly set the transformer circuit
used.

You can calculate the ohmic and inductive voltage drop using the following
formulas. This voltage drop calculation relates to the relativized voltage on
the secondary side of the voltage transformer.
Formula for calculating the ohmic voltage drop:
Formula for calculating the inductive voltage drop:
U
r
Ohmic line parameter in Ω/km
U
