1. What is Power Transmitted Using Load Current?

Power Transmitted Using Load Current in a 2-Phase 4-Wire Overhead System refers to the actual power delivered through the system, calculated based on the current, maximum voltage, and phase difference between voltage and current.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( P \) — Power Transmitted (W)
• \( I \) — Current Overhead AC (A)
• \( V_m \) — Maximum Voltage Overhead AC (V)
• \( \Phi \) — Phase Difference (rad)
• \( \cos \) — Cosine function
• \( \sqrt{2} \) — Square root of 2

Explanation: The formula accounts for the RMS conversion factor (√2) and the power factor (cosΦ) in a 2-phase system to calculate the actual power transmitted.

3. Importance of Power Calculation

Details: Accurate power calculation is essential for system design, efficiency analysis, load management, and ensuring proper operation of electrical distribution systems.

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: Why is the √2 factor used in the formula?
A: The √2 factor converts the maximum voltage to RMS voltage, which is used for power calculations in AC systems.

Q2: What is the significance of phase difference in power calculation?
A: Phase difference determines the power factor, which affects the actual power delivered in AC circuits.

Q3: Can this calculator be used for single-phase systems?
A: No, this specific formula is designed for 2-phase 4-wire overhead systems. Single-phase systems use different formulas.

Q4: What are typical values for phase difference?
A: Phase difference typically ranges from 0 to π/2 radians (0-90 degrees), with 0 indicating purely resistive load.

Q5: How accurate is this calculation for real-world applications?
A: This provides a theoretical calculation. Real-world systems may require additional factors for complete accuracy.
