The voltage can be controlled at the voltage measuring point or at the load point in the electrical power
system. In this case, the load-point voltage is calculated on the basis of the measured load current and the
known impedance between the voltage measuring point and the load point.
The following figures show possible configurations of the voltage controller for two-winding transformers
with and without current measurement.
