1. What is Constant Using Line Losses?

The Constant Overhead AC is defined as the constant of line of an Overhead supply system in a 2-Phase 4-Wire configuration. It represents the relationship between power transmission parameters and line losses in the system.

2. How Does the Calculator Work?

The calculator uses the formula:

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

Where:

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

Explanation: The formula calculates the system constant based on the relationship between transmitted power, line characteristics, and power losses in the overhead transmission system.

3. Importance of Constant Calculation

Details: Accurate calculation of the system constant is crucial for designing efficient overhead transmission systems, optimizing power delivery, and minimizing energy losses in 2-Phase 4-Wire configurations.

4. Using the Calculator

Tips: Enter all values in appropriate units (power in watts, length in meters, voltage in volts, resistivity in ohm-meters, and losses in watts). All values must be positive numbers greater than zero.
