Fig. 6. Application example for the voltage regulator SPAU 341 C1. The overcurrent blocking and
the undervoltage blocking features complement each other, as the voltage is measured from phases
L1 and L2 and the current from phase L3. Load shedding in two stages. Stage 1 reduces the set
voltage by half the setting value RSV, and stage 2 reduces the set voltage to the full extent of setting
value RSV. Tap-changer operation feedback is connected to the regulator. Tap-changer position is
measured.
