The formula to calculate the phase to phase voltage (Vpp) is:
\[ V_{pp} = V_{ln} \times \sqrt{3} \]
Where:
Let's say the line to neutral voltage (\( V_{ln} \)) is 230 Volts. Using the formula:
\[ V_{pp} = 230 \times \sqrt{3} \]
We get:
\[ V_{pp} \approx 230 \times 1.732 \approx 398.36 \]
So, the phase to phase voltage (\( V_{pp} \)) is approximately 398.36 Volts.
Phase to phase voltage, also known as line to line voltage, is the voltage measured between any two phases in a three-phase system. It is used to power large motors and other heavy loads. The phase to phase voltage is typically higher than the line to neutral voltage and is calculated by multiplying the line to neutral voltage by the square root of 3 (approximately 1.732).
