2.4.3 Voltage balance
The uneven load on the conductor and the direct connection of greater
power ratings can cause deviations from the ideal voltage waveform and
unbalanced voltages in three-phase AC supply systems.
If this condition is not fulfilled, or symmetry at the connection location is not
known, the use of a main choke in the mains-side feeder unit of the power
bus is recommended.

In the project planning consider only AC power networks that
handle permitted asymmetric divergences in the mains voltage
