What is the formula use for calculation voltage and current in star and delta?
Balanced Star (Wye) Connected Systems:Line Voltage = 1.732 x Phase VoltageLine Current = Phase CurrentBalanced Delta Connected Systems:Line Voltage = Phase VoltageLine Current = 1.732 x Phase Current
In a 3-phase high voltage star-star connection 140KVA transformer and load phase voltage is 115v and frequency is 400hz what is the total load current?
Maximum load current on a 140KVA, three phase transformer when the output voltage is 115 v phase to phase is: 140kva / sqrt (3) / 115 = 703 Amps. frequency does not matter here.
How is the neutral point in a star connection created?
In a distribution transformer's star-connected secondary, the common point of connection is called the 'star point' and is connected to earth. The star point then provides the neutral connection for the transformer secondary, providing a return path for any unbalanced currents due to an unbalanced three-phase load.This arrangement provides a four-wire distribution system, comprising three line conductors and one neutral conductor (in addition, there are various methods of providing an earth connection to consumers). The line-to-line voltage is called a line voltage (in the UK, 400 V), while a line-to-neutral voltage is called a phase voltage (in the UK, 230 V). The line voltage being 1.732 x phase voltage.
How line voltage is equal to root three phase voltage for star connected load?
Let's start with the correct terminology. The three energised, or 'hot', conductors are called 'line' conductors (not 'phase') conductors. which (surprise, surprise!) is why the voltages across them are called 'line voltages'.In the case of a star (wye) connected, three-phase, four-wire, system each phase is connected between a line and the neutral. And, yes, the line voltage is indeed root-3 (or 1.732) times the phase voltage.If the lines are labelled a, b, c, and the neutral is labelled N, then line voltage Vab is equal to the phasor (vector) sum of phase voltage Van and phase voltage Vnb, which are displaced from each other by 60 electrical degrees. The length of the resulting phasor is 1.732 times either of these phase voltage.
G1 phase s pase and g2 phase is called?
Interphase
What is the early phase of the star called once the gas and dust begin to coalesce into a sphere?
It is called as a PROTOSTAR
What is the early phase of mitosis called?
prophase
What is the phase of a star called where it simply cools and fades away?
The phase of a star where it cools and fades away is called the white dwarf phase. During this stage, the star no longer undergoes nuclear fusion and gradually loses its heat and brightness over billions of years.
What is the phase of a star called where it cools and fades away?
minecraft pork
Stage where the star swells?
The stage where a star swells into a red giant is called the red giant phase, typically occurring when a star runs out of hydrogen fuel in its core and starts to fuse helium in its shell. During this phase, the star expands and cools, turning redder in color due to its lower surface temperature.
What is the early form of a star?
That's called a "protostar".
What does each phase look like and what are they called?
each phase looks like an ocean star and if you have woken up with it you can see it shines brightly
Was mercantilism an early phase of capitalism?
That is true, mercantilism was an early phase of capitalism.
What is the name for the portion of a star life cycle when it is using hydrogen for fuel?
The phase of a star's life cycle where it is using hydrogen as fuel is called the main sequence phase. During this phase, a star converts hydrogen into helium through nuclear fusion in its core to produce energy and maintain its stability.
Is the Evening Star really a star?
No, the "evening star" is actually the planet Venus. It has an eccentric orbit around the sun which allows it to be seen in the early evening as well as the early morning ( also called the "morning star").
In what phase were meteorites formed?
early phase
What is the early phases of the star called once the gas and dust begin to coalesce into a sphere?
It is called as a PROTOSTAR
