the connection here meant for the connection of windings in three core or limbs of a transformer. it might be delta or star connected.


Do I need tertiary winding in a auto transformer with vector YNynO?

Depends, do you need to connect auxiliaries/generator/capacitor/reactor to tertiary? If not you may consider to not to use tertiary. The 3rd harmonic current will become an issue then. The phase to ground Isc will be lower.

Can you replace DY11 by DYN11 transformer?

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.

What is the difference between an ordinary transformer and a center-tapped transformer?

An ordinary transformer has two input/output terminals but a center tapped transformer has 2 input and 3 output terminals. One is taken from the center for a ground connection. This causes it to get 50% of the actual value. And ordinary transformer contains 2 windings. An autotransformer has one.


What is importance of vector group of transformer?

The vector group of a transformer is important for determining the phase relationship and polarity of the transformer windings. It helps ensure proper operation and connection of the transformer in the electrical system. Additionally, the vector group is essential for parallel operation of transformer units to avoid phase shifts and ensure synchronization.
