On a wye connection all three ends of the phase winding coils are connected together and grounded. The other end of the three phase winding are connected to the supply voltage.

Why is 277 3 phase called DELTA and 208 3 phase called Y It seems to you they have pretty much same attributes?

408 volts x 1.73 = 277 volts is the star ( Y ) point of 3 phase 480V. A transformer connected in a Delta configuration is different than a Y or Star configuration. 277 volts is a voltage that is used in industrial plants usually for lighting. The following link will explain the whole star delta connection. http://www.allaboutcircuits.com/vol_2/chpt_10/6.html


What is a Y current?

A Y current is the electric current through one branch of the star arrangement of a three-phase circuit.


Application of Y-delta transformations?

Y-delta transformations are used in electrical engineering to convert circuits from a Y configuration to a delta configuration or vice versa. This conversion simplifies analysis and calculations for circuits with complex interconnections by reducing the number of elements to consider. It is commonly used in power distribution systems and control systems to optimize system performance and efficiency.


What size wire for 225 amp 208 volt 3 phase circuit y.?

For a 225 amp 208 volt 3 phase circuit, you would typically need to use a 3/0 AWG copper wire or a 250 kcmil aluminum wire. Be sure to consult with local electrical codes and regulations to ensure compliance with specific requirements for your installation.


Why the voltage applied to each winding in a STAR configuration of three phase is reduced?

In a star configuration, often called "Y", the voltage across one winding is from a phase to ground. Phase to phase you have voltage across 2 windings. And at the risk of confusing you, the phase to phase voltage is not double the other because the windings are only 120 degrees out of phase and not 180 degrees. To calculate this you take the voltage of one winding, 120v for example, and multiply by the square root of 3, or about 1.732, and get 208v. Or you take 277v and get 480v.


What changes mechanical energy into electrical energy that can be transported through the power grid?

A three phase alternator (sometimes incorrectly called a generator or AC generator) is a device that changes rotational mechanical energy into electrical energy. The power grid transmits three phase electrical power (usually in Delta configuration) from electricity suppliers to local distribution systems; which then distributes the electrical power as either three phase Delta configuration, three phase Y configuration, two phase, or single phase power depending on the needs if the users.


Why Y phase is high in YNyn0 when doing magnetic balance test?

because y phase is y phase ...it is not b phase or R phase so it is high


Capacity of transformer is 1600 kva.11kv system. in our company y phase continuosly taking high loads then R phase and B phase .due to that y phase cables in capacitor bank and mcc panels opencircuiti?

If one of the phases continuously takes a high load with a poor power factor it might have tripped a circuit breaker in the capacitor bank.


What type of three phase voltage provides a stinger or high leg?

Currently, in popular usage, 3 phase systems are arranged in a "Y" or "star" configuration with the same voltage from each leg to ground. Primary sides of transformers are in a delta, "triangle", configuration but this is not the utilized side. In some old systems, the utilized system is delta with the mid point of one winding grounded. The phases at each end of this winding will measure half the volts to ground as from phase to phase. The phase farthest from the grounded winding measures a much higher voltage to ground than phase to phase since, in simple terms, it is measuring the voltage across 1 and 1/2 windings.


How do you get 208 voltage?

208 volts is the phase to phase voltage on a three phase low voltage system. In a split single phase service, the voltage is 120/240. In a three phase service, the voltage is 120/208. This is due to using a different transformer configuration. In the above, the first number is the phase to neutral reading, and the second is the phase to phase reading. For example, 120/240 and 120/208 both provide 120v on standard receptacles, but when using a dryer, or hot water heater, for example, that appliance would be using 240v or 208v, respectively.


What tripositive ion has the electron configuration of Kr 4d3?

The trivalent ion with the electron configuration of Kr 4d^3 is the Yttrium (Y^3+) ion. Yttrium differs from krypton (Kr) by losing three electrons to achieve the electron configuration of Kr 4d^3.
