Want this question answered?
Star Wars Transformers was created in 2006.
Technically Transformers don't have genders but most personify him as a male.
You can find star wars transformers at Walmart That remark was unnessary. Star wars transformers are stuff from starwars that are able to transform into another thing. Like a giant robot or a fighter jet. Things like that.
No, he does not.
I believe they are, and they are still both hot.
hahahaa
By using the star- delta starting methodBy using variable rhoestatsBy using auto transformers
in order to reduce the impact of fault current...
because usually the step down transformers are used for supply so it requires neutral(return)path, we cant take neutral path through delta connection hence the star connection is used and mostly in step-down the star connection is used.
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.
two contecter <<>> There are three contactors used in a Star Delta configuration.
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.
The inrush current is reduced. This is the reason for star delta starters. Motor starts on star and after about 10 to 15 seconds, depending on the load of the motor, it switches to a delta configuration to run.
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.
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).
Using star delta method of wiring you can run high rated motor with out any high starting current. Star connection can provide 3 phase power as well as single phase load
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
