A transformer that increases voltage is a step-up transformer.
The footprint of a transformer foundation depends on the size and weight of the transformer, as well as the specific design requirements to support and securely hold the transformer in place. Typically, the foundation will be sized to provide adequate support and stability for the transformer, as well as to distribute the weight evenly across the ground to prevent sinking or shifting.

To wire a buck-boost transformer from 208V to 240V, connect the 208V input leads to the appropriate taps on the transformer to step up the voltage. The output leads on the transformer will then provide 240V. Be sure to consult the transformer's wiring diagram and follow all safety guidelines during installation.
In series, yes. In parallel, nope! Putting a Yd1 transformer in series with a Dy11 transformer would result in the output of the Dy11 transformer being identical to the input of the Yd1 transformer with the exception of the voltage magnitude - this will change depending on the winding ratio's on both transformers. But, in regards to other properties of the voltage, the phases will in be in phase, with the voltage in-between the two transformers lagging by 30 degrees.
Yes, you can replace a DY11 transformer with a DYN11 transformer, but it is important to consider the differences in their winding configurations and phase shifts. The DY11 transformer has a wye (star) connection on the primary side and a delta connection on the secondary side, while the DYN11 transformer has a delta connection on the primary side and a wye connection on the secondary. This change in configuration may affect voltage levels and phase relationships in your system, so it's essential to ensure compatibility with existing equipment and load requirements. Always consult with an electrical engineer before making such a replacement.
By calculate do you mean calculate the connections required or phasor diagrams? full question would be helpful
synchronise means parallel operation. to do so first you must understand the winding level chaos. what is 30 deg and -30 deg. then automatically you can come to a conclusion
there is no specification of Dy11.. it will be Dyn11.. it is the vector group of the transformer. capital d means primary winding is delta secondary winding is star(y) and the secondary current lags voltage by 30degree this angle when shown in clock will be looking like 11 o clock
The difference between a Dy11 (delta winding lags the wye winding by 30 degrees) and a Dy1 (delta winding leads the wye winding by 30 degrees) is a phase shift. One is not better than another in a general sence. Depending on the configuration of the plant and surrounding power lines and transformers, one may be more beneficial than the other by allowing the plant to sync to the grid through multiple sources without first disconnecting.

Transformer has windings
yes we can place auto transformer in place of original transformer
The function of fans in a transformer is to regulate the transformer's temperature.

Center tap transformer is the such kind of transformer that is made to a point half way along a winding of a transformer.
