1. What is Power Transmitted Using Area of X-Section?

Power Transmitted Using Area of X-Section calculates the amount of power that can be transferred through an underground AC wire system, taking into account the cross-sectional area of the wire and other electrical parameters in a 3-phase 4-wire US configuration.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ P = V_m \times \cos(\Phi) \times \sqrt{\frac{A \times P_{\text{loss}}}{2 \times \rho \times L}} \]

Where:

\( P \) — Power Transmitted (W)
\( V_m \) — Maximum Voltage Underground AC (V)
\( \Phi \) — Phase Difference (rad)
\( A \) — Area of Underground AC Wire (m²)
\( P_{\text{loss}} \) — Line Losses (W)
\( \rho \) — Resistivity (Ω·m)
\( L \) — Length of Underground AC Wire (m)

Explanation: This formula calculates the maximum power that can be transmitted through an underground AC wire system while accounting for voltage, phase difference, wire characteristics, and power losses.

3. Importance of Power Transmission Calculation

Details: Accurate power transmission calculation is crucial for designing efficient electrical distribution systems, optimizing energy transfer, minimizing losses, and ensuring proper sizing of electrical components in underground AC systems.

5. Frequently Asked Questions (FAQ)

Q1: Why is the area of cross-section important in power transmission?
A: The cross-sectional area directly affects the current-carrying capacity and resistance of the wire, which impacts power transmission efficiency and losses.

Q2: What factors affect line losses in underground AC systems?
A: Line losses are influenced by wire material, length, cross-sectional area, current magnitude, and operating temperature.

Q3: How does phase difference affect power transmission?
A: Phase difference (power factor) affects the real power component that can be effectively transmitted through the system.

Q4: What are typical resistivity values for common conductor materials?
A: Copper: ~1.68×10⁻⁸ Ω·m, Aluminum: ~2.82×10⁻⁸ Ω·m at 20°C.

Q5: How does wire length impact power transmission capability?
A: Longer wires have higher resistance, leading to increased voltage drop and power losses, reducing the effective power transmission capability.
