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 derived from the volume of conductor material and the phase difference in a two-phase three-wire overhead system.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ K = \frac{V \cdot (\cos(\Phi))^2}{1.457} \]

Where:

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

Explanation: The formula calculates the system constant by considering the volume of conductor material and the squared cosine of the phase difference, divided by the constant factor 1.457.

3. Importance of Constant Calculation

Details: Accurate calculation of the overhead AC constant is crucial for designing efficient overhead power transmission systems, optimizing conductor material usage, and ensuring proper system performance.

4. Using the Calculator

Tips: Enter the volume of conductor in cubic meters and phase difference in radians. Both values must be positive numbers for valid calculation.

5. Frequently Asked Questions (FAQ)

Q1: What is the significance of the 1.457 constant?
A: The 1.457 constant is a derived factor specific to this calculation that accounts for system characteristics in two-phase three-wire overhead systems.

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

Q3: What are typical values for Volume of Conductor?
A: Volume values vary based on system requirements but typically range from small fractions to several cubic meters depending on conductor size and length.

Q4: How does phase difference affect the constant?
A: As phase difference increases, the cosine term decreases, resulting in a lower calculated constant value for the same conductor volume.

Q5: Can this calculator be used for single-phase systems?
A: No, this specific formula and calculator are designed for two-phase three-wire overhead systems only.
