Checking and setting line drop compensation (LDC)
A load current of ≥ 10 % of the nominal transformer current is needed for the
following function tests.
1. Press to select manual mode.
2. Set parameters for line drop compensation and Z compensation to 0.
3. Select the control deviation (dV) display on the main screen (press
if
necessary).
The measured voltage must be within the bandwidth.
4. Set line drop compensation Vr to 20.0 V.
The control deviation dV must be negative.
5. Set line drop compensation Vr to -20.0 V.
The control deviation dV must be positive.
If the control deviation appears in the opposite direction, change the polarity
of the current transformer.
6. Set line drop compensation Vr to the operating value you want.
