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

The Power Transmitted using Area of X-Section formula calculates the amount of electrical power that can be transmitted through an underground AC wire system, taking into account the cross-sectional area of the wire and various electrical parameters.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ P = V_m \times \cos(\Phi) \times \sqrt{\frac{A \times P_{loss}}{4 \times \rho \times L}} \]

Where:

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

Explanation: This formula calculates the maximum power that can be transmitted through an underground AC wire system while considering 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, minimizing energy losses, and ensuring proper sizing of electrical components in underground AC networks.

4. Using the Calculator

Tips: Enter all values in appropriate units. Maximum voltage, area, resistivity, and length must be positive values. Phase difference and line losses should be non-negative values.

5. Frequently Asked Questions (FAQ)

Q1: What is the significance of the 4 in the denominator?
A: The factor of 4 accounts for the specific configuration of the 2-phase 4-wire underground AC system being analyzed.

Q2: How does wire area affect power transmission?
A: Larger wire cross-sectional area generally allows for higher power transmission capacity and reduces resistive losses in the system.

Q3: What is the role of phase difference in power transmission?
A: Phase difference (power factor) affects the efficiency of power transfer. A higher power factor (cosΦ closer to 1) results in more efficient power transmission.

Q4: How do line losses impact power transmission?
A: Line losses represent energy dissipated as heat in the transmission system. Higher losses reduce the efficiency of power delivery to the end user.

Q5: When is this calculation particularly important?
A: This calculation is critical when designing new underground electrical distribution systems or upgrading existing infrastructure to ensure optimal performance and efficiency.
