Note that the entire regulating range of the on-load tap-changer is traveled
through during automatic synchronization. This allows strong voltage
changes to occur on the transformer. Therefore, carry out the automatic
synchronization on a de-energized transformer.
Conditions for automatic synchronization:
▪ The motor-drive unit is in "Local" operating mode.
▪ The motor protective switch is switched on (position I).
▪ The motor voltage is below the permissible range.

The automatic synchronization is carried out.
9.19.2 Multi-column on-load tap-changer model
In the multi-column design of the on-load tap-changer, you can carry out the
synchronization automatically. To do so, the on-load tap-changers are
moved across the entire regulating range. All on-load tap-changers are con-
trolled simultaneously.
Note that the entire regulating range of the on-load tap-changer is traveled
through during automatic synchronization. This allows strong voltage
changes to occur on the transformer. Therefore, carry out the automatic
synchronization on a de-energized transformer.
Conditions for automatic synchronization
▪ The motor-drive unit is in "Local" operating mode.
▪ The motor protective switch is switched on (position I).
▪ The motor voltage is below the permissible range.
