1. What is Current Per Phase Calculation?

The current per phase calculation determines the electrical current flowing through each phase in a three-phase solar panel system. This is essential for proper system design, component selection, and safety considerations.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( I_{total} \) — Total current in the system (amperes)
• \( I_{phase} \) — Current per phase (amperes)

Explanation: In a balanced three-phase system, the total current is divided equally among the three phases.

3. Importance of Phase Current Calculation

Details: Accurate phase current calculation is crucial for selecting appropriately sized cables, circuit breakers, and inverters. It ensures system safety, efficiency, and compliance with electrical codes.

4. Using the Calculator

Tips: Enter the total system current in amperes. The value must be greater than zero. The calculator will automatically compute the current per phase.

5. Frequently Asked Questions (FAQ)

Q1: When is this calculation applicable?
A: This calculation applies to balanced three-phase solar systems where current is evenly distributed across all phases.

Q2: What if my system is unbalanced?
A: For unbalanced systems, phase currents must be measured individually, and this simple division won't apply.

Q3: Does this account for power factor?
A: No, this is a simple calculation assuming unity power factor. For precise calculations, power factor should be considered.

Q4: How does this relate to voltage in three-phase systems?
A: While this calculator focuses on current, remember that three-phase systems have both line-to-line and line-to-neutral voltages that affect power calculations.

Q5: Can I use this for DC solar systems?
A: No, this calculation is specifically for AC three-phase systems. DC systems use different calculations.
