1. What is Volume of Conductor Material when Resistance is Given?

The Volume of Conductor Material when Resistance is Given calculation determines the 3-dimensional space enclosed by a conductor material in a 3-phase 4-wire underground AC system based on electrical parameters and system characteristics.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ V = \frac{7 \times R \times A \times P^2 \times L}{P_{loss} \times V_m^2 \times \cos(\Phi)^2} \]

Where:

\( V \) — Volume of Conductor (m³)
\( R \) — Resistance Underground AC (Ohm)
\( A \) — Area of Underground AC Wire (m²)
\( P \) — Power Transmitted (Watt)
\( L \) — Length of Underground AC Wire (Meter)
\( P_{loss} \) — Line Losses (Watt)
\( V_m \) — Maximum Voltage Underground AC (Volt)
\( \Phi \) — Phase Difference (Radian)
