Line Phase Voltage Calculator
Use Line Phase Voltage to convert line voltage to phase voltage. The loaded example shows the arithmetic with practical electrical units.
Enter values for wye phase voltage
Use one consistent electrical operating case for all fields.
How Line Phase Voltage works
The arithmetic follows Vphase,wye = Vline ÷ √3. Line Phase Voltage uses Line-to-line voltage to report Wye phase voltage.
With the loaded values, wye phase voltage evaluates to 230.94 V. A second case makes the effect of one changed measurement visible.
Inputs for Line Phase Voltage
Line-to-line voltage belong to Line Phase Voltage. Keep source units with line-to-line voltage.
Loaded numbers demonstrate the calculation; they are not equipment recommendations. Replace them with values from the case being evaluated.
- Line-to-line voltage
- Example entry: 400 V.
Reading the Line Phase Voltage result
This output represents Line Phase Voltage.
The result informs selection but does not approve a component or installation.
Measurement and units
Use RMS quantities unless a field explicitly asks for peak amplitude. Check prefixes on line-to-line voltage.
Matching units and measurement locations prevent false differences. Power factor can be checked in Power Factor Calculator.
Limits of this calculation
Confirm whether the load is connected in wye or delta. Use Phase Shift Time Calculator to convert a time offset into phase angle.
The result reflects the formula scope, not every connected component. Unentered effects remain outside Line Phase Voltage. For impedance magnitude, use Series RLC Impedance Calculator.
