1. What is Line Losses Using Volume Of Conductor Material?

Line Losses Using Volume Of Conductor Material calculates the power losses in a 2-wire mid-point DC system based on the conductor material's volume and other electrical parameters. This helps in designing efficient power transmission systems.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ P_{line} = \frac{4 \times \rho \times (P^2 \times l^2)}{(V_m^2 \times V)} \]

Where:

\( P_{line} \) — Line Losses (W)
\( \rho \) — Resistivity (Ω·m)
\( P \) — Power Transmitted (W)
\( l \) — Length of Wire DC (m)
\( V_m \) — Maximum Voltage (V)
\( V \) — Volume Of Conductor (m³)

Explanation: The formula calculates power losses in transmission lines by considering the material properties, transmitted power, line length, voltage, and conductor volume.
