3 Phase Current Calculator

Formula

To calculate the 3 Phase Current (I3):

\[ I3 = \frac{VA}{V} \]

Where:

\(I3\) is the 3 Phase Current (amps)
\(VA\) is the Volt-Amps
\(V\) is the Voltage (volts)

What is 3 Phase Current?

The 3 Phase Current is the current flowing in a three-phase electrical system. It is calculated by dividing the total volt-amps by the voltage. This calculation is essential in electrical engineering to ensure that electrical systems are designed and operated safely and efficiently.

Example Calculation

Let's assume the following values:

Volt-Amps (\(VA\)) = 3000 VA
Voltage (\(V\)) = 400 V

Using the formula:

\[ I3 = \frac{3000}{400} = 7.5 \text{ amps} \]

The 3 Phase Current is 7.5 amps.
