7.3.13.5 Setting Z compensation
Z compensation can be used for example for minor changes to the phase an-
gle φ. It can also be used for meshed grids. Z compensation is not however
dependent on phase angle φ.
To correctly set the parameters, you need to calculate the voltage increase
(ΔV) taking the current into account.
