1. What is the Area of X-Section Formula?

The formula calculates the cross-sectional area of overhead AC wire for a two-phase three-wire system. It considers power transmission requirements, material properties, and system losses to determine the optimal wire size.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ A = \frac{(2+\sqrt{2}) \times P^2 \times \rho \times L}{(\cos(\Phi))^2 \times 2 \times P_{loss} \times V_m^2} \]

Where:

\( A \) — Area of Overhead AC Wire (m²)
\( P \) — Power Transmitted (Watt)
\( \rho \) — Resistivity (Ω·m)
\( L \) — Length of Overhead AC Wire (m)
\( \Phi \) — Phase Difference (rad)
\( P_{loss} \) — Line Losses (Watt)
\( V_m \) — Maximum Voltage Overhead AC (Volt)

Explanation: The formula accounts for power transmission efficiency, material resistance, and system characteristics to determine the optimal wire cross-section.
