# How do you Calculate phase voltage from line voltage?

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

Line voltage to phase voltage calculator: Phase voltage V(L-N) in volts is equal to line voltage V(L-L) in volts divided by root 3. Example: Calculate the phase voltage of the star-connected alternator output voltage of 11000 V line to line. V(L-N) = 11000 / 1.732 = 6350 Volts.

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

Line voltage is the voltage measured between any two lines in a three-phase circuit. Phase voltage is the voltage measured across a single component in a three-phase source or load. Line current is the current through any one line between a three-phase source and load.

**What is line voltage formula?**

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

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

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.

### What is line line voltage?

The line to line voltage is the voltage between any two of the three phase wires ABC, e.g. Vab. With delta, there is no neutral wire available and so the voltage between any two of the three available phase wires is the line voltage by default.

### What is the line voltage?

Definition of line voltage : the voltage of a power transmission circuit or distribution circuit up to the point of transformation or utilization.

**What is the difference between 415V and 440V?**

If given 440 V instead of 415 V, the 6 % (440/415*100) increase in voltage will cause more magnetizing current to flow in the stator. and the power factor of the motor will be low. Also, the core loss will increase because of increased flux in the motor. The torque delivering capacity will increase by (1.06*1.06=12 %).

**What is line voltage?**

## How do you Calculate phase and line current?

## What is the line voltage of 3-phase?

A three-phase connection, on the other hand, consists of three separate conductors that are needed for transmitting electricity. In a single-phase power supply system, the voltage may reach up to 230 Volts. But on a three-phase connection, it can carry a voltage of up to 415 Volts.

**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 Calculate phase voltage and phase current?**

Three Phase Power and Current

- kW = kVA x pf.
- kVA = kW/pf.
- kVA = kW / power factor = 23/0.86 = 26.7 kVA (26700VA)
- Current = VA / voltage = 26700 / 230 = 116 A.
- VLL =√3 x VLN
- VLN = VLL / √3.
- kVA = kW / power factor = 12 / 0.86 = 13.9 kVA (13900 VA)
- Current = VA / voltage = 13900 / 230 = 60 A.

### What is the relation between line voltage and phase voltage in delta connection?

Answer: As we know, in a delta connection (second figure), the line voltage and phase voltage are equal. While for a star connection line voltage is higher than phase voltage which is given by the relation: Vline = √3 Vphase.
