1. What is the K(Two-Wire One Conductor Earthed) Calculator?

The K(Two-Wire One Conductor Earthed) Calculator calculates the constant of line for an overhead DC supply system using the formula that relates power transmitted, resistivity, length of wire, line losses, and maximum voltage.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ K = \frac{4 \times P^2 \times \rho \times L^2}{P_{loss} \times V_m^2} \]

Where:

\( K \) — Constant Overhead DC
\( P \) — Power Transmitted (Watt)
\( \rho \) — Resistivity (Ω·m)
\( L \) — Length of Wire DC (Meter)
\( P_{loss} \) — Line Losses (Watt)
\( V_m \) — Maximum Voltage Overhead DC (Volt)

Explanation: This formula calculates the system constant based on the relationship between transmitted power, material properties, and system losses.

3. Importance of Constant Overhead DC Calculation

Details: The constant K is important for designing and analyzing overhead DC transmission systems, helping engineers optimize system performance and minimize losses.
