1. What is Maximum Voltage using Load Current?

Maximum Voltage Overhead AC is defined as the peak amplitude of the AC voltage supplied to the line or wire in a Single-Phase Two-Wire Mid-Point Overhead System.

2. How Does the Calculator Work?

The calculator uses the Maximum Voltage formula:

Where:

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

Explanation: This formula calculates the maximum voltage by considering the transmitted power, current flow, and phase difference between voltage and current in the AC system.

3. Importance of Maximum Voltage Calculation

Details: Accurate maximum voltage calculation is crucial for proper system design, insulation selection, and ensuring safe operation of overhead AC transmission systems.

4. Using the Calculator

Tips: Enter power in watts, current in amperes, and phase difference in radians. All values must be valid (power > 0, current > 0, phase difference ≥ 0).

5. Frequently Asked Questions (FAQ)

Q1: Why is the square root of 2 used in the formula?
A: The square root of 2 converts RMS values to peak values in AC systems, as maximum voltage is the peak voltage.

Q2: What is the significance of phase difference in this calculation?
A: Phase difference accounts for the power factor in the system, which affects the relationship between voltage, current, and power.

Q3: What are typical maximum voltage values for overhead systems?
A: Maximum voltage values vary depending on the system design and application, ranging from hundreds to thousands of volts.

Q4: Are there limitations to this formula?
A: This formula assumes ideal conditions and may need adjustments for real-world factors like line losses, harmonics, and system impedance.

Q5: Can this formula be used for three-phase systems?
A: No, this specific formula is designed for single-phase two-wire mid-point systems. Three-phase systems require different calculations.
