1. What is Power Transmitted Using Current In Each Outer (2-Phase 3-Wire US)?

Power Transmitted Using Current In Each Outer (2-Phase 3-Wire US) refers to the amount of electrical power that is transferred through a 2-phase 3-wire underground AC system, calculated using the current in each outer conductor.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ P = I \times V_m \times \cos(\Phi) \]

Where:

\( P \) — Power Transmitted (Watt)
\( I \) — Current Underground AC (Ampere)
\( V_m \) — Maximum Voltage Underground AC (Volt)
\( \Phi \) — Phase Difference (Radian)

Explanation: This formula calculates the real power transmitted in a 2-phase 3-wire underground AC system by multiplying the current, maximum voltage, and cosine of the phase difference.

3. Importance of Power Calculation

Details: Accurate power calculation is essential for designing efficient electrical distribution systems, determining system capacity, and ensuring proper load management in underground AC networks.

4. Using the Calculator

Tips: Enter current in amperes, maximum voltage in volts, and phase difference in radians. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is the significance of phase difference in power calculation?
A: Phase difference represents the angular displacement between voltage and current waveforms, and its cosine (power factor) determines the proportion of apparent power that does real work.

Q2: How does this differ from single-phase power calculation?
A: While the basic formula P = VIcos(Φ) is similar, 2-phase 3-wire systems have different conductor configurations and power distribution characteristics compared to single-phase systems.

Q3: What are typical values for underground AC systems?
A: Underground AC systems typically operate at voltages ranging from 240V to 35kV, with currents varying based on load requirements and system design.

Q4: Why use maximum voltage instead of RMS voltage?
A: The formula uses maximum voltage (peak voltage) rather than RMS voltage because the calculation is based on the peak values in the AC waveform.

Q5: Are there limitations to this calculation method?
A: This calculation assumes balanced loads and ideal conditions. Actual system performance may vary due to factors like line losses, harmonic distortion, and unbalanced loads.
