The current is the same in the three live wires. The voltage can be described as the line voltage (phase to neutral) or the phase voltage (phase to phase) which is larger by a factor of sqrt(3).
So a line voltage of 230 v corresponds to a phase voltage of 400 v.

What is phase current?
A phase current is the current passing through a phase, whereas a line current is the current flowing through a line.
How three phase line current convert in single phase?
The current is the same in the three live wires. The voltage can be described as the line voltage (phase to neutral) or the phase voltage (phase to phase) which is larger by a factor of sqrt(3). So a line voltage of 230 v corresponds to a phase voltage of 400 v.
Is rms is line current or phase current?
RMS (root mean square) value can refer to either line current or phase current, depending on the context of the electrical system being discussed. In a three-phase system, the RMS line current is the current flowing in the lines connecting the power source to the load, while the RMS phase current is the current flowing through each phase of the load. For balanced loads in a three-phase system, the RMS line current and phase current have specific relationships, but they are distinct concepts.
Why line current is greater than phase current in delta connection?
Because if you apply Kirchhoff's Current Law to the junction between the line current and the two phase currents, the line current is the phasor (vector) sum of two phase currents. For a balanced load (only), this works out to 1.732 x phase current.
How do you convert 440 voltage line to voltage phase?
To convert a 440V line voltage to phase voltage in a three-phase system, you divide the line voltage by the square root of 3 (approximately 1.732). This means the phase voltage is calculated as ( V_{phase} = \frac{V_{line}}{\sqrt{3}} ). For 440V line voltage, the phase voltage would be approximately 254V.
What is the proof line current is equal to square root of 3 times of phase currents?
In a three-phase system, the line current (I_L) and phase current (I_Ph) relationship can be derived from the configuration of the system. For a balanced load in a star (Y) connection, the line current is equal to the phase current (I_L = I_Ph). In a delta (Δ) connection, the line current is equal to the phase current multiplied by the square root of 3 (I_L = √3 * I_Ph) due to the geometry of the connections and the phase angle relationships, resulting in the factor of √3 that arises from the 120-degree phase shifts between the currents. Thus, for a delta connection, the line current is greater than the phase current by that factor.
Can you convert 415v 3 phase to 230v single phase?
415V 3 phase is the line to line voltage. The line to neutral of this supply is 230V single phase. Therefore you use one of the phases and the neutral.
Write dowen the relationshipbetween line and phase the 3phase system if voltageline and currentline are line value voltage power and current power are phase value?
A-for star connectionE(line)=1.73E(Phase)I(line)=I(Phase)&B-for delta connectionE(line)=E(Phase)I(line)=1.73I(Phase)
In delta connection what is formula for phase current?
Line current = 1.732 x Phase CurrentCommentOnly for balanced loads.
What is difference between line current and phase current?
A phase current is the current passing through a phase, whereas a line current is the current flowing through a line.In the case of a balanced delta-connected load, IL = 1.732 IP. In the case of a balanced star-connected load, IL = IP.For unbalanced loads, these relationships don't hold true, and must be individually calculated.
What is the connection of normal wire star or delta?
normally delta connection wired in 3 phase induction motor. during starting wiring is in Star and after running normal speed changeover to delta .beacause starting time its phase voltage equals less root3 times of line voltage ,line current and phase current equals. in Delta phase voltage and line voltage equals, and phase current equals root3 times line current
What is the difference between Load Current Line Current and Phase Current?
A load current is a current drawn by an electrical load. In other words, it is the current flowing from the source to the load.For a single-phase system, a line current is a current flowing through the line, or 'hot', conductor, while the current through the neutral conductor is called the neutral current.For a three-phase system, the three 'hot' conductors between the load and the source are called 'lines' and, so, the currents passing through them are called 'line currents'. For a three-phase system, loads are either connected between line conductors (delta-connected system) or between each line and the neutral (star- or wye-connected system), and represent the phases -so the currents passing through the loads are called 'phase currents'.For a balanced three-phase system, the line current is 1.732 times the value of a phase current, where the phases (loads) are connected in delta. For phases (loads) connected in star (or 'wye') the line current is numerically-equal to the phase currents.
