In the realm of electrical engineering, understanding and calculating neutral current is crucial for the safety and efficiency of three-phase power systems. The Neutral Current Formula Calculator emerges as a vital tool for professionals and students alike, simplifying the complex process of calculating the neutral current in a three-phase system. This calculator is designed to provide accurate and reliable calculations, ensuring electrical systems are well-balanced and safe.
Formula of Neutral Current Calculator
To calculate the neutral current in a three-phase system, the calculator uses the following formula:
I_neutral = √(I_line1^2 + I_line2^2 + I_line3^2 - I_line1 * I_line2 - I_line2 * I_line3 - I_line3 * I_line1)
Where:
I_neutralis the neutral current.I_line1,I_line2, andI_line3are the currents in each of the three phases.
This formula is essential for determining the current flowing through the neutral wire, which can be critical for system design and troubleshooting.

Example of Neutral Current Calculator
Let’s illustrate the use of the formula with a practical example. Assume we have a three-phase system with the following phase currents:
I_line1 = 10AI_line2 = 15AI_line3 = 20A
Applying the formula:
I_neutral = √(10^2 + 15^2 + 20^2 - 10 * 15 - 15 * 20 - 20 * 10) = √(100 + 225 + 400 - 150 - 300 - 200) = √275A
This calculation reveals the neutral current in the system, which is crucial for ensuring the system’s safety and efficiency.
