What is the angle between phase current and line current?
21.3 (b) that the angle between the line (phase) current and the corresponding line voltage is (30 + ø)0 for a lagging load. Consequent, if the load is leading, then the angle between the line (phase) current and corresponding line voltage will be (30 – ø)0.
What is the angle of phase difference between the line current and phase current in a star connected system?
N-Phase Star System: 9.25(a). Its vector diagram is shown in Fig. 9.25(b). The angle of phase difference between adjacent phase voltages is 360°/n.
What is phase angle between line and phase voltage?
Now, let us say, the voltage across R and Y terminal of the star connected circuit is VRY. Now, as angle between VR and VY is 120o(electrical), the angle between VR and – VY is 180o – 120o = 60o(electrical). Thus, for the star-connected system line voltage = √3 × phase voltage.
What is the relation between line current and phase current in delta connection?
In a delta system, the line current is greater than the phase current by the square root of 3, which is about 1.732). In a wye system, the line current equals the phase current.
What is the relation between line current and phase current in star connection of transformer?
Three-phase Voltage and Current
| Connection | Phase Voltage | Line Current |
|---|---|---|
| Star | VP = VL ÷ √3 | IL = IP |
| Delta | VP = VL | IL = √3 × IP |
What is line current formula?
Line current is I(L) in Amps is equal to root 3 times of the phase current I(P) in amps. Example: What is the line voltage of the delta connected system whose phase current is 500 Amps? I(L) = 500 x 1.732 = 866 Amps.
What is the angle difference between each phase in Wye Connection?
The angle between the phases is 120 degrees. In a balanced system (no capacitive or inductive reactance) the angle between the line voltage and line current is zero.
What is difference between line and phase voltage?
Phase Voltage is a voltage given between the phase and the neutral. (Note that neutral is only available in star connection and not in delta connection.) Line Voltage is a phasor potential of a phase wire in connection with another phase wire.
When the angle between phase voltage and phase current is zero its power factor is?
When the power factor equals zero (0), the phase angle between the current and the voltage will be 90o as: cos-1(0) = 90o. In this case the actual power consumed by the AC circuit is zero regardless of the circuit current.
What is the relation between line current and phase current in 3 phase delta connection?
i.e. In Delta Connection, The Line current is √3 times of Phase Current. As, all the Line current are equal in magnitude i.e.
What is the angular relationship between line current and phase current in a balanced delta connected three phase system?
Line current is equal to the phasor difference of the current in two phases connected to the line, i.e. Where, IR, IY, and IB are the phase current in delta connection. For a balanced system, the phasor diagram is given below. Line voltage lags behind phase current by an angle equal to the power factor angle φ.
What is the relation between line current phase current and line voltage phase voltage for Star & delta connection?
In star connection, phase voltage is 1/√3 times the line voltage. For Delta connection, the line voltage and phase voltage are equal.
