Tap Changer

Clicking a power transformer with tap changer opens a control dialog. In the dialog, you
can monitor the voltage and the current tap changer position.
Figure 3.6.6-1 Tap Changer Control dialog
Depending on the device and the configuration, you can manually lower or raise the
relative position of the tap changer, or assign a specific position by entering a numeric
value.
You must have the required user permissions to perform these
changes, and local/remote switch must allow the operation.
The tap changer must also be in manual operating mode.
The Operation mode tab shows the auto/manual and single/parallel operation modes
of the tap changer. You can change the modes of the tap if you have the required user
permissions. The operation modes must be supported by the IED support and allowed
by the local/remote. If they are not, the options are not available in the dialog.
