Power Transmitted in a 3-Phase 4-Wire Overhead System is defined as the total power delivered through all three phases of the electrical network, calculated from the power transmitted per single phase.
The calculator uses the formula:
Where:
Explanation: The formula calculates the total power transmitted in a 3-phase system by taking one-third of the power transmitted per phase, accounting for balanced distribution across all three phases.
Details: Accurate power calculation is essential for designing electrical systems, ensuring proper load distribution, maintaining system stability, and optimizing energy efficiency in 3-phase networks.
Tips: Enter the power transmitted per phase in watts. The value must be valid (greater than 0).
Q1: Why is the factor 1/3 used in the formula?
A: The factor 1/3 is used to calculate the total power from per-phase power in a balanced 3-phase system, distributing the power equally across all three phases.
Q2: What is the difference between per-phase power and total power?
A: Per-phase power refers to the power in a single phase, while total power is the sum of power across all three phases in a balanced system.
Q3: Can this formula be used for unbalanced systems?
A: This formula assumes a balanced 3-phase system. For unbalanced systems, individual phase powers must be calculated separately and summed.
Q4: What units should be used for input values?
A: Input values should be in watts (W) for power. Ensure consistent units for accurate results.
Q5: How does this apply to real-world electrical systems?
A: This calculation is fundamental in power system analysis, helping engineers design and maintain efficient and reliable 3-phase electrical networks.
