1. What is Length Using Volume Of Conductor Material (Two-Phase Three-Wire OS)?

Length Using Volume Of Conductor Material (Two-Phase Three-Wire OS) calculates the length of an overhead AC wire based on the volume of conductor material, line losses, phase difference, maximum voltage, resistivity, and power transmitted in a two-phase three-wire overhead system.

2. How Does the Calculator Work?

The calculator uses the formula:

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

Where:

\( L \) — Length of Overhead AC Wire (m)
\( V \) — Volume of Conductor (m³)
\( P_{loss} \) — Line Losses (W)
\( \Phi \) — Phase Difference (rad)
\( V_m \) — Maximum Voltage Overhead AC (V)
\( \rho \) — Resistivity (Ω·m)
\( P \) — Power Transmitted (W)

Explanation: This formula calculates the length of overhead AC wire by considering the volume of conductor material, power losses, electrical properties, and system parameters in a two-phase three-wire configuration.

3. Importance of Length Calculation

Details: Accurate length calculation is crucial for proper power transmission system design, minimizing energy losses, optimizing material usage, and ensuring efficient electrical distribution in overhead AC systems.

4. Using the Calculator

Tips: Enter all values in appropriate units (volume in m³, line losses in W, phase difference in radians, maximum voltage in V, resistivity in Ω·m, and power in W). All values must be positive numbers.
