1. What is the Transmitted Power Calculation?

The Transmitted Power calculation determines the amount of power that can be efficiently transferred through a DC three-wire system, considering line losses, conductor material volume, maximum voltage, resistivity, and wire length.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ P = \sqrt{\frac{P_{line} \times V \times (V_m)^2}{5 \times \rho \times (l)^2}} \]

Where:

\( P \) — Power Transmitted (Watt)
\( P_{line} \) — Line Losses (Watt)
\( V \) — Volume Of Conductor (m³)
\( V_m \) — Maximum Voltage (Volt)
\( \rho \) — Resistivity (Ω·m)
\( l \) — Length of Wire DC (Meter)

Explanation: This formula calculates the optimal power transmission capacity while accounting for energy losses in the system and the physical properties of the conductor material.

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 conductors for DC three-wire configurations.

4. Using the Calculator

Tips: Enter all values in appropriate units (Line Losses in Watt, Volume in m³, Maximum Voltage in Volt, Resistivity in Ω·m, Length in Meter). All values must be positive numbers greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: Why is this calculation specific to DC Three-Wire systems?
A: This formula is optimized for DC three-wire configurations, which have different characteristics and requirements compared to single-wire or AC systems.

Q2: What factors affect power transmission efficiency?
A: Conductor material resistivity, wire length, cross-sectional area, operating voltage, and system configuration all significantly impact transmission efficiency.

Q3: How does conductor volume affect power transmission?
A: Larger conductor volume typically allows for higher current carrying capacity and reduced resistance, enabling more efficient power transmission with lower losses.

Q4: What are typical resistivity values for common conductors?
A: Copper has resistivity of approximately 1.68×10⁻⁸ Ω·m, while aluminum has about 2.82×10⁻⁸ Ω·m at 20°C.

Q5: How accurate is this calculation for real-world applications?
A: While this provides a good theoretical estimate, real-world applications should consider additional factors like temperature variations, insulation properties, and environmental conditions.
