Star Star Transformer
Star Star Transformer is formed in a 3 phase transformer by connecting one terminal of each phase of individual side, together. The common terminal is indicated by suffix 1 in the figure below. If terminal with suffix 1 in both primary and secondary are used as common terminal, voltages of primary and secondary are in same phase. That is why this connection is called zero degree connection or 0o - connection.
If the terminals with suffix 1 is connected together in HV side as common point and the terminals with suffix 2 in LV side are connected together as common point, the voltages in primary and secondary will be in opposite phase. Hence, Star Star Transformer connection is called 180o - Connection, of three phase transformer.

What is the voltage phase shift between primary and secondary line voltages in star-delta transformer connection?
The voltage phase shift between primary and secondary connections in a transformer is 180 electrical degrees.
How do you convert 480v to 120v?
to derive 120 volts from 480 volts you have to use a transformer, based on your needs. If you needed 100 amps at 120 volt single phase you would need a 12kva transformer. This is just an example.
Is there a neutral on a three phase transformer?
It depends on whether you are wye or delta connected. A transformer is a transformer, and a three phase transformer is simply three transformers. The key is in how you hook them up.AnswerIt depends on how the transformer is connected. If one set of windings is connected in star (or wye), then the star point is/canbe earthed and becomes the neutral for that particular connection; this is the standard connection for the secondary (low-voltage) of European distribution transformers. In North American three-phase distribution transformers, the secondary windings are connected in delta, and one phase is centre tapped, earthed, and that becomes the neutral point for a 240/120-V split-phase supply to a residence.This answer applies to both three-phase transformers, and to single-phase transformers which have been connected to form a three-phase transformer bank. (It is incorrect to say that a three-phase transformer is simply three single-phase transformers!)
What is DY11 transformer?
A DY11 transformer is a three-phase transformer configuration where the high voltage winding is connected in a delta (Δ) configuration and the low voltage winding is connected in a star (Y) configuration. This configuration is commonly used in power distribution systems to step down high voltage to a lower voltage for industrial and commercial applications.

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.
What is centre tap transformer?
In electronics, a center tap is a connection made to a point half way along a winding of a transformer or inductor, or along the element of a resistor or a potentiometer. ..
