1. What is Constant Using Volume of Conductor Material?

The Constant Underground AC is defined as the constant of line for a 2 Phase 3 Wire US underground 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:

\[ K = \frac{V \times (\cos(\Phi))^2}{2.914} \]

Where:

\( K \) — Constant Underground AC
\( V \) — Volume of Conductor (m³)
\( \cos(\Phi) \) — Cosine of Phase Difference
2.914 — Constant factor

Explanation: The formula calculates the system constant by considering the volume of conductor material and the power factor (cosine of phase difference) in the electrical system.

3. Importance of Constant Calculation

Details: Accurate calculation of system constants is crucial for proper electrical system design, load balancing, and ensuring efficient power transmission in underground 2 Phase 3 Wire US systems.

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).
