1. What Is The Length Using Volume Of Conductor Material(1 Phase 3 Wire US) Calculation?

This calculation determines the length of underground AC wire based on conductor volume, line losses, phase difference, maximum voltage, resistivity, and power transmitted. It's essential for proper electrical system design and efficiency optimization.

2. How Does The Calculator Work?

The calculator uses the formula:

\[ Length = \sqrt{\frac{Volume Of Conductor \times Line Losses \times (\cos(Phase Difference) \times Maximum Voltage Underground AC)^2}{(10) \times Resistivity \times (Power Transmitted^2)}} \]

Where:

\( Volume Of Conductor \) — Conductor material volume (m³)
\( Line Losses \) — Power losses in the line (W)
\( Phase Difference \) — Phase angle difference (rad)
\( Maximum Voltage Underground AC \) — Peak AC voltage (V)
\( Resistivity \) — Material resistivity (Ω·m)
\( Power Transmitted \) — Total power being transmitted (W)

Explanation: This formula calculates the optimal wire length considering material properties, electrical characteristics, and power transmission requirements.
