Formula

The formula for calculating line current (I) in a three-phase electrical circuit is:

where:

• I is the line current,
• V is the voltage, and
• Z is the impedance.

Example Solve

Let’s say we have a three-phase system with a voltage (V) of 480 volts and an impedance (Z) of 20 ohms. Plugging these values into the formula:

So, the line current (I) in this example is 24 amps.

FAQs
