1. What is Constant Using Line Losses (1-Phase 2-Wire US)?

The Constant Underground AC is defined as the constant of line of a Overhead supply system. It represents a calculated value used in electrical engineering to characterize transmission line properties.

2. How Does the Calculator Work?

The calculator uses the formula:

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

Where:

\( K \) — Constant Underground AC
\( \rho \) — Resistivity (Ω·m)
\( P \) — Power Transmitted (W)
\( V_{ac} \) — Voltage Underground AC (V)
\( P_{loss} \) — Line Losses (W)
\( V_m \) — Maximum Voltage Underground AC (V)

Explanation: This formula calculates the line constant based on material resistivity, transmitted power, operating voltages, and power losses in the system.

3. Importance of Constant Calculation

Details: Accurate calculation of line constants is crucial for designing efficient power transmission systems, optimizing energy transfer, and minimizing power losses in underground AC networks.
