## What is the relationship between line and phase voltage?

When the line voltage increases, the phase voltage will also increase. When phase voltage increases, it will be reflected in the increase in line voltage.

**What is the relation between phase voltage and line voltage phase current and line current in delta connected three phase system?**

Three-phase Voltage and Current

Delta | VP = VL | IL = √3 × IP |

**What is the relationship of per phase voltage and line to line voltage in a balanced wye connected load?**

Also, voltage magnitude across each phase of a Wye-connected load to neutral, or the phase-voltage ( ), is equal to the line-to-neutral voltage ( ) of the line supplying the load. The line-to-neutral voltage is equal to the line-voltage ( ) divided by .

### What is the relationship between phase and line voltages and currents in a delta connection?

i.e. In Delta Connection, The Line current is √3 times of Phase Current.

**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.

**How do you find line current and phase current?**

Line current to phase current calculator: Phase current I(P) in Amps is equal to line current I(L) in Amps divided by root 3. Example: Calculate the phase current of the delta connected alternator output line current of 1500 Amps. I(P) = 1500 / 1.732 = 866 Amps.

#### How do you determine Wye or Delta?

A wye system is connected in a “Y” shape, or configured in a star shape. In a delta system configuration, the phase voltage is equal to the line voltage. In a wye system configuration, the phase voltage is equivalent to the line voltage divided by the root of 3.

**What is the relation between line current phase current and line voltage phase voltage for Star & delta connection?**

3. In star connection, line voltage is √3 times the phase voltage. In star connection, phase voltage is 1/√3 times the line voltage. For Delta connection, the line voltage and phase voltage are equal.

**What is the relation between line current phase current and line voltage phase voltage for Star & Delta Connection?**

## What is the relation between line current and phase current in case of 3 phase star connected circuit?

The same current flows through phase winding as well as in the line conductor as it is connected in series with the phase winding. Hence, in a 3 Phase system of star connections, the line current is equal to phase current.

**How do you Calculate phase and line current?**

**How do you Calculate line voltage from phase voltage?**

Phase voltage to line voltage calculator: Line voltage is V(L-L) in volts equal to root 3 times of the phase voltage V(L-N) in volts. Example: What is the line voltage of the delta connected system whose phase voltage is 240 Volts. V(L-L) = 240 x 1.732 = 415 Volts.

### What is the relationship between line voltage and phase voltage?

The line and phase voltage are directly proportional to each other. Therefore, if we give an increment to the line voltage, then it will also result in an increase of phase voltage. The line current in the star connection is currently flowing through a single-phase or line and the phase current is the current flowing between two phases.

**What is the difference between phase current and line current?**

While line current = phase current. In delta connection, all the three ends of the phases are connected to form a closed triangular loop, and it has no common neutral point as in a star connection. Here, the line and phase voltage are related as follows: While line current = √3× phase current. 1.

**What is the angle between line current and line voltage?**

the angle between the line currents and the corresponding line voltage is with current lagging by an angle (for lagging loads). This is evident from Figure 3; the current inline and phase are the same.

#### What is Lineline voltage in a three-phase system?

Line voltage in a three-phase system is the potential difference between any two lines or phases present in the system, denoted by V line or V L-L. The phases present here are conductors or windings of a coil.
