R&X compensation
R&X compensation (LDC) requires exact cable data. Line voltage drops can
be compensated very accurately using LDC.
To set R&X compensation correctly, you need to calculate the ohmic and in-
ductive 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:
