To perform a star-delta connection using a push button, you typically use a control circuit that includes relays or contactors. First, the push button is used to start the motor in star configuration, allowing for reduced voltage and lower starting current. After a predetermined time (often using a timer), the control circuit switches from the star to the delta configuration, allowing the motor to run at full voltage. This setup requires appropriate wiring and safety measures to ensure proper operation and protection of the motor.

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

Why the load must be delta connection instead using star connection?
in order to reduce the impact of fault current...
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
How do you get two different voltages using the delta - star connection?
A star connection is where the three phase nonpolarities are tied to a single point, and very often grounded. A delta connection is where the nonpolarity of one phase is tied to the polarity of another phase, forming a greek delta shape. If measuring from polarity to nonpolarity on a single phase, in the star formation you are looking at L-N voltages; in the delta connection, you are looking at L-L voltages (L-N voltages * square root of three).
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
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.
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.
Can you make star delta connection with 2 contractors?
yes

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.

How do you wire a three phase motor with two speed?

What happens when a phase gets short and also when it get opened in a delta and star connection?
In star connection when two phase is short,it work as single phase system. In delta when one phase is open ,it work as a single phase.
