20150035538 | METHOD FOR MONITORING AN ON-LOAD TAP CHANGER - The invention relates to a method for monitoring an on-load tap changer that is used to switch between winding taps of a tapped transformer without interrupting the load current and is actuated using a motor drive. According to the invention, prior to the actual load switching process, the on-load tap changer is initially moved a short distance, preferably against the direction in which the load is subsequently switched. In said initial process, it is verified whether the on-load tap changer has moved, i.e. has left its previous stationary position, and/or whether the torque on the motor drive has exceeded a predefined threshold value. The actual load switching process takes place only once the test has yielded a positive result. | 02-05-2015 |

20160035506 | METHOD FOR AVERAGING THE VOLTAGE IN AN ON-LOAD TAP CHANGER - The invention relates to a method for averaging the voltage in an on-load tap changer used to switch between various winding taps of a tapped transformer. The general inventive concept consists in reaching a predefined operating position of the on-load tap changer by having a parameterized control device activate a motor drive in a first rotational direction once the on-load tap changer has been turned on, such that the on-load tap changer starts running through its stationary operating positions, i.e. the various winding taps of the tapped transformer, in the direction of the first tap; the control device recognizes when the on-load tap changer has reached its final position, whereupon the motor drive is activated in a second rotational direction such that the on-load tap changer then runs through the control range in the opposite switching direction until reaching the first stationary operating position; the first stationary operating position is subsequently configured as a predefined operating position using the control device parameterization stored in a non-volatile manner. | 02-04-2016 |
