ABB tap changers for power transformers. A de energized tap changer is a switch, which is connected to the winding taps of the transformer. When the tap changer is moved from one position to another, the amount of the tap winding connected into the circuit is changed. This permits the adjustment of the voltage ratio of the transformer to best suit the voltage requirements at the transformer. Off-load tap-changing mechanisms require the transformer to be isolated before its tap settings can be adjusted, and is normally the case with smaller distribution transformers. On-load tap-changing can be performed with the transformer supplying its load, usually automatically, in response to changes in its secondary voltage..

Off-load tap changing transformer; On-load tap changing transformer; Off-load tap-changing transformer. In this method, the transformer is disconnected from the main supply when the tap setting is to be changed.. Offload Tap Changers for Transformers Off-load tap changers for transformers (DETC) are used to change the transmission ratio in order to adjust the transformer to grid conditions. Therefore tap changer for transformers have several pins to connect with the coil windings.. Another use of off tap changers in the three-phase transformers respect to the passage of a coupling of the windings in series with a star connection. Une autre utilisation concerne le passage d'un branchement en parallèle à un branchement en série des enroulements de chaque phase..
