Tap Changing: Automatic
For automatic tap changing, the mini-ATOS tap control output must be connected to the tap
changer control unit for both directions. In the transformer profile, Tap Changer tab, the tap control
must be also activated.
During the automatic tap changing, the tap switch message will be shown like Figure 82. The
system sends a pulse to change the tap position and waits for the trigger. When the trigger came,
DRM graph will be shown and the results will be recorded.
