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 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.
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.
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 cools and fades away?
minecraft pork
What is the phase of a star called where it simply cools and fades away?
minecraft pork
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
Stage where the star swells?
Near the death of a star, the star swells and this phase is known as red giant phase.
Was mercantilism an early phase of capitalism?
That is true, mercantilism was an early phase of capitalism.
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 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.
Star-star connection of transformer?
Star Star TransformerStar Star Transformer is formed in a 3 phase transformer by connecting one terminal of each phase of individual side, together. The common terminal is indicated by suffix 1 in the figure below. If terminal with suffix 1 in both primary and secondary are used as common terminal, voltages of primary and secondary are in same phase. That is why this connection is called zero degree connection or 0o - connection.If the terminals with suffix 1 is connected together in HV side as common point and the terminals with suffix 2 in LV side are connected together as common point, the voltages in primary and secondary will be in opposite phase. Hence, Star Star Transformer connection is called 180o - Connection, of three phase transformer.Vikram Meena
