1. What is Constant Using Volume of Conductor Material?

The Constant Overhead AC is defined as the constant of line of an Overhead supply system. It represents a calculated value based on the volume of conductor material and the phase difference in the system.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( K \) — Constant Overhead AC
• \( V \) — Volume of Conductor (m³)
• \( \Phi \) — Phase Difference (radians)
• \( \cos \) — Cosine trigonometric function

Explanation: The formula calculates the constant value based on the volume of conductor material and the cosine squared of the phase difference, divided by 0.625.

3. Importance of Constant Calculation

Details: Accurate constant calculation is crucial for designing and analyzing overhead AC supply systems, ensuring proper system performance and efficiency.

4. Using the Calculator

Tips: Enter volume of conductor in cubic meters and phase difference in radians. All values must be valid (volume > 0, phase difference ≥ 0).

5. Frequently Asked Questions (FAQ)

Q1: What is the significance of the 0.625 factor?
A: The 0.625 factor is a constant derived from system design parameters and helps normalize the calculation for standard overhead AC systems.

Q2: Why is cosine squared used in the formula?
A: The cosine squared term accounts for the power factor effect in the system, which significantly impacts the constant calculation.

Q3: What units should be used for phase difference?
A: Phase difference should be entered in radians for accurate calculation with the trigonometric functions.

Q4: How does conductor volume affect the constant?
A: Larger conductor volumes typically result in higher constant values, indicating different system characteristics.

Q5: Can this calculator be used for DC systems?
A: No, this calculator is specifically designed for single-phase three-wire overhead AC systems.
