Abstract
An on-load tap changer for a tapped transformer has a controller configured to actuate the on-load tap changer; and a storage unit. A method of operating the tap changer includes: carrying out a switching operation of the on-load tap changer by the controller; updating at least one data record stored in the storage unit depending on the switching operation carried out; checking on a basis of the updated data record whether a locking condition is met, by the controller; and blocking further switching operations based on determining that the locking condition is met, by the controller.
