Description
Step voltage of the tap changer is up to 900 V and the number of positions is up to 9. These parameters are sufficient for on-load voltage regulation on transformers of MV distribution networks. Switching takes place in vacuum interrupters. The VT is selected when an oil transformer of the 40.5 kV class has to regulate voltage without disconnecting consumers.
