measuring arrangement.
3. Measure actual voltage and compare with the measured value dis-
played on the device's main screen.
4. Press key several times to display the operating values for current,
power and phase angle and compare them with values of the operating
measuring instruments.
5. Control the on-load tap-changer manually with the or keys until
the measured voltage (V
actual
) reaches the desired voltage (V
desired
) set in
the next stage.
6. Set desired value 1 to the value you want.
7. Set bandwidth in relation to step voltage [► 73].
8. Set delay time T1 to 20 seconds [► 75].
9. Set control response T1 to linear [► 76].
10. Press to raise the on-load tap-changer 1 step.
11. Press to select auto mode.
ð After 20 seconds, the device returns the on-load tap-changer to the
original operating position.
