star delta connection is used reduce high starting current of the motor.
you can see the below diagram
if you need anything more details... let me know

Where do you use star-star connection in electrical system?
i think its use for 3 phase connection.
How many terminals in star connection?
6
How will the speed and the slip of the motor change with increasing load in star wye and delta connection?
the speed decrease if increasing load..in star connection the speed lower
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.
Why the load must be delta connection instead using star connection?
in order to reduce the impact of fault current...
How the angular momentum of earth is constant explain how?
T=I A(alpha) , T = I * DALTA W (OMEGA)/DALTA T , SINCE I*W (OMEGA) = DALTA L(ANGLUAR MOMENTUM ) So, T = DALTA L / DALTA T , Thus , As rate of change of anguar momentum is equal to torque . so we know that earth revolves around sun while torque acting on it is zero . so here we may conclude that T=DALTA L / DALTA T , T= O => np change in DALTA L i.e DALTA L = CONSTANT . so now we may conclude that when earth revolves aroung sun angkuar momentum is constant.
When was University of Perpetual Help System DALTA created?
University of Perpetual Help System DALTA was created in 1975.
What is the definition of star connection?
The definition of star connection is a connection of the ends of phase windings at the star point.
How do you convert star delta connection to delta star connection?
hahahaa
What is black rivers morass coastal features?

What is the Scottish Gaelic for foster child?
Dalta is the word for foster child.
What are star connection?
Compared with what?
What is the star point of a CT?
The term, 'star point', refers to the common point of connection for the three windings of a star-connected (wye-connected) transformer connection. The star point is usually earthed (grounded) and provides the neutral point of the connection.
Why does an electromagnetic brake designed for a star connection not work in delta?
Probably the reason is in the different voltages between the star and delta connection voltages. An electromagnetic brake designed for the lower voltage of the star connection would burn out or open when introduced to the higher voltage of the delta connection.
Why phase current is equal to line current in star connection?
Because it is the same current, as you can determine by examining a circuit diagram of a star connection.
