Star and Delta is used mostly in 3 pH networks where 3 phases are 120 degrees apart. consider A1-A2,B1-B2, C1-C2 as three different wdgs or resistors. for star connection connect A2,B2,C2 together and A1, B1,C1 wil be 3 terminals where we can give 3 pH supply. for Delta , form a triangle by Connnecting C2-A1,A2-B1,B2-C1 .

How do you convert star delta connection to delta star connection?
hahahaa
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.
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 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
Can you make star delta connection with 2 contractors?
yes
How much you can save the power from converting star delta connection to star connection?
The power of a three-phase load is the sum of the three individual loads. It makes no difference whether they are connected in star (wye) or in delta.
What is the difference between a Y - delta starter and a star - delta starter?
No difference. Y is used as a symbol to indicate the star connection.
Show the wiring connection and star delta control panel?

Why do we use star to star connection in motor?
In a high voltage installation, with the same power, current drawn is small compared to those in low voltage. However it requires a thicker insulation, thus cost of insulation is significant compared to the conductor cost. By using a star connected winding, the insulation voltage required is equal to line to neutral connection, otherwise if it is connected in delta the insulation rating has to be provided for a line to line connection. Despite having a higher current, the total cost is still lower compared to using a higher insulation rating.
How many contactors are used in a star-delta starter?
3 contactors are used: one for the main incoming service lines, one to make the star connection and one for the delta connection. Auxiliary to the contactors, a delay timer, adjustable from 500-1000 seconds, is used to shift from star to delta configuration.
