3 Product description
The device serves to keep constant the output voltage of a transformer with
an on-load tap-changer.
To do this, the device compares the transformer's measured output voltage
(V
actual
) with a defined desired voltage (V
desired
). The difference between V
actual
and V
desired
is the control deviation (dV).
If the control deviation is greater than the specified bandwidth (B%), the de-
vice emits a switching pulse after a defined delay time T1. The switching
pulse triggers an on-load tap-changer tap change which corrects the trans-
former's output voltage.
The device parameters can be optimally adjusted to the line voltage behavior
to achieve a balanced control response with a small number of tap-change
operations of the on-load tap-changer.
The following diagram (on page 19) shows an overview of voltage regulation.
