1. What is Maximum Voltage using Volume of Conductor Material?

Maximum Voltage using Volume of Conductor Material calculates the peak voltage in a 2-wire mid-point earthed overhead DC system based on the conductor material properties and system parameters. This calculation helps in determining the optimal voltage level for efficient power transmission.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ V_m = \sqrt{\frac{\rho \cdot (P \cdot L)^2}{P_{loss} \cdot V}} \]

Where:

\( V_m \) — Maximum Voltage Overhead DC (V)
\( \rho \) — Resistivity of conductor material (Ω·m)
\( P \) — Power Transmitted (W)
\( L \) — Length of Wire DC (m)
\( P_{loss} \) — Line Losses (W)
\( V \) — Volume of Conductor (m³)

Explanation: This formula calculates the maximum voltage by considering the relationship between power transmission, conductor properties, and system losses.

3. Importance of Maximum Voltage Calculation

Details: Calculating maximum voltage is crucial for designing efficient power transmission systems, ensuring proper insulation levels, and optimizing conductor material usage while maintaining acceptable power losses.

4. Using the Calculator

Tips: Enter all values in appropriate units (resistivity in Ω·m, power in watts, length in meters, losses in watts, volume in cubic meters). All values must be positive numbers greater than zero.
