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.
Circiut diagram of star delta connection?
i don't know please help
When was The Delta Star created?
The Delta Star was created in 1983.
How do you change star to delta?
In motor starters, this is usually done using contactors. Explanation of this can easily be done using a circuit diagram. There are three contactors, the main, star and delta contactors-all these contactors can be the same type. There are many ways of wiring a star delta but here I will only give a generalized answer. First, the main contactor and star contactors are energised thus the motor runs in star. After about 5 seconds, the timer which gets energized at the same time as the main and star contactors, switches its CONTACTS i.e the normally open closes and the normally close opens. This dienergize the star contactor and energized the delta contactor. Thus, the motor now runs in delta.
How do you convert star delta connection to delta star connection?
hahahaa
What type of star is the delta star?
A delta star is a mathematical technique to simplify the analysis of an electrical network, not a "real" star.A delta star is not a its a mathematical formulasee related link
Should a star-delta motor be supplied wye or delta power?
A star-delta motor should be supplied star-delta.Wye is simply another name for star. Star-delta motors use a star or wye configuration to start, and a delta configuration to run. This reduces the voltage on the windings during the high current starting time.
Star delta control circuit diagram?
The Star-Delta control circuit diagram shows the delta contact and the main contact.
Delta star transformation?
it is the mathematical analysis which shows relationship b/w various resistors connected in star or delta form's using the transformation process we can convert delta into star or viceversa
What is a manual star-delta starter?
In manual star delta starter, the change over from star to delta does not happen automatically. The operator or user puts on the starter, and after few seconds he pushes a lever or handle to change over to Delta. In automatic method, change over happens from star to delta using an automatic preset timer.
What is the current drawn in star as compared to delta?
Star voltage is 1 / 1.732, or 0.577 delta voltage. (1.732 is the square root of 3.) It follows, then, that star current is 0.577 delta current.Not asked, but answered for completeness, star power is 0.5772, or 0.3333 delta power. This is why large motors use a star-delta start sequence - to minimize startup thermal stress.
