1. What is Maximum Voltage using Line Losses (Two-Phase Three-Wire OS)?

The Maximum Voltage using Line Losses (Two-Phase Three-Wire OS) formula calculates the peak voltage in a two-phase three-wire overhead system considering power transmitted, line losses, and other electrical parameters. It helps in designing efficient power transmission systems.

2. How Does the Calculator Work?

The calculator uses the formula:

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

Where:

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

Explanation: The formula accounts for power transmission efficiency, material properties, and electrical characteristics to determine the maximum voltage in the system.
