4.1 Function description of the voltage regulation

The device keeps the output voltage of a transformer with an on-load tap-
changer constant.
The device compares the transformer's measured voltage (U
fined reference voltage (U
the control deviation dU.
The device parameters can be adjusted to the line voltage behavior to
achieve a balanced control response with the on-load tap-changer only per-
forming a small number of tap-change operations.
