Your use of the word "bushings" implies you are dealing with a high-voltage transformer (over 600 volt). A three phase STEP-DOWN transformer normally has 3 bushings on the Primary side regardless of whether it is star-delta or another type. The Secondary side might have 3 or 4. A single phase transformer normally has 2 bushings on the Primary side and 2 or 3 on the Secondary side. If the transformer is being used to STEP-UP, it would be reversed from above. If this does not answer your question, I need more info.

What is the meaning of DY 11 on a transformer nameplate?
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
Why step up transformers you using Star delta connection?
Star-delta connections in transformers are primarily used to manage voltage levels and reduce starting currents in three-phase systems. When a step-up transformer is connected in a star configuration, it allows for higher line-to-line voltages and improved efficiency during normal operation. Upon starting, a delta connection can reduce the initial inrush current, minimizing stress on the electrical system. This configuration effectively balances performance and safety in industrial applications.
Is Mewtwo Delta species a rare card?
if it has a star at the bottom corner then yes it is
How many missions did the voyager go on?
They only got issued 1 mission by Star Fleet to the Bad Lands where they were pulled to the Delta Quadrant by an energy wave sent by "The Caretaker".
Is it possible to get to the delta quadrant in flash trek broken mirror?
In Flash Trek: Broken Mirror, players can explore different quadrants of the Star Trek universe, including the Delta Quadrant. While the game primarily focuses on the Alpha and Beta Quadrants, certain missions or gameplay elements may allow access to the Delta Quadrant. However, the specifics can depend on the game's version and updates. Players should check for any particular missions or scenarios that facilitate travel to the Delta Quadrant.
What are the problems associated with the three-phase transformer connection?
One must check the design of the transformer windings. STAR - Delta or Star to star or Delta - star or Delta Delta. Wiring must be done accordingly.
Where is the use of earth transformer?
It is used in where the transformer are connected in star delta.

Why we use delta-star transformer instead of star-star transformer in a consumer plant.?
There is a problem called "neutral phase shift" in star-star transformer, if we connect unbalance load(single phase load at secondary), then the phase point is shifted towards neutral. we require sinusoidal secondary voltage at secondary, for this flux must be sinusoidal. Flux will be sinusoidal, if it contains the third harmonic component of exciting current. so third harmonic current can not flow in star-star transformer. so we use delta-star transformer,in delta , third harmonic component can flow & get sinusoidal output.
The Most suitable and economically connection for small high voltage transformer is?
delta star
What is the principal use in star - delta transformer connection?
i thinkecause he like sit idkk
Is 3 phase star transformer has more winding than delta?
The # of windings in a transformer are based on the primary and secondary voltages the transformer is rated for not the way the windings are connected.
Differentiate star to delta connection of a transformer?
Star has one red, one yellow, one blue and neutral phases seperatelly. Delta has all four in sequence, combined.
How do you calculate current on delta to star transformer?
To calculate the current on a delta to star transformer, first identify the line current in the delta configuration (I_line). The phase current in the star (wye) configuration (I_phase) can be calculated using the formula: I_phase = I_line / √3. This relationship arises because the line current in a delta system is √3 times the phase current in a star system. Therefore, knowing the line current allows you to easily find the phase current in the star configuration.
What is The Connection in three phase transformer?
the connection here meant for the connection of windings in three core or limbs of a transformer. it might be delta or star connected.
How do you connect an earthing transformer with delta connected secondary?
You have to connect each phase (R,Y & B respectively) of earthing transformer zig zag winding to each phase of power transformer delta secondary respectively. Then the zig zag winding of earthing transformer star point to be earthed.
