A star winding has a red yellow and blue phases. The centre point of every stay winding is used as d nuetral point. Hence the star winding in a transformer enables a nuetral point.

The Most suitable and economically connection for small high voltage transformer is?
delta star
Why is star connection used in a three phase transformer?
The power of all three phases can be transmitted on three conductors.A star connection, as opposed to a delta, provides a grounding reference. Also, for ground faults on the secondary (assuming no delta third winding, or source third winding) will be a direct ratio similar to phase faults, instead of 57%. Another reason is to avoid the inherent phase shift involved in a delta/star configured transformer.Another AnswerA 'star-connected' secondary is the standard European connection for a three-phase distribution transformer, as it provides a line voltage of 400 V together with a phase voltage (i.e. line to neutral) of 230 V.
How can a delta circuit be converted into a star circuit?
With a transformer...
What is a forward-reverse star delta?
A forward reverse star delta is a two in one motor starter where a motor first runs on star connection and then changed to delta connection after a time which has been set. The motor direction can be changed, whether forward or reverse
Differentiate delta to delta connection of the transformer to delta to Y connection?
In delta to delta there will be no ground on both primary and secondary sides. Leave the primary side but we take care on secondary side. If there any fault occurs on the secondary then there will be unbalanced voltages between the phases results in the flow of current through the secondary windings so only we are using star on the secondary side while having neutral to prevent such a current flow.
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.
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.
What is the principal use in star - delta transformer connection?
i thinkecause he like sit idkk
The Most suitable and economically connection for small high voltage transformer is?
delta star
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 convert star delta connection to delta star connection?
hahahaa

Where is the use of earth transformer?
It is used in where the transformer are connected in star delta.
Why we get the 0 level in trans farmer when we use delta to star connection when you get the 220 volts at each terminals of star connection of transformer how we get 0 level or neutral equals to 0?
A: In the USA there is D delta connection or Y connection. The Y center point may not be zero if there is circulating current due to mismatch of the phases

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.
