3 Phase Amp Calculator

The 3 phase amp calculator is a simple yet powerful tool that helps in calculating the current flowing in a three-phase electrical system. It is particularly useful for electricians, engineers, and anyone working with complex electrical systems to ensure the proper functioning and safety of equipment. By accurately determining the current in each phase, users can prevent overloading circuits, select appropriate protective devices, and optimize energy consumption.

Formula

The formula for calculating the three-phase current is: Current (I) = √3 x Line Voltage (V) x Power Factor (PF) / Load Impedance (Z) Where: – Current (I) is the calculated output in amperes – Line Voltage (V) is the voltage of the electrical system – Power Factor (PF) is the ratio of real power to apparent power – Load Impedance (Z) is the impedance of the load in ohms

How to Use

1. Enter the line voltage and power factor values into the corresponding input fields. 2. Input the load impedance value in the designated field. 3. Click the “Calculate” button to determine the three-phase current. This calculator ensures a seamless and accurate conversion/calculation process.

Example

Suppose you have a three-phase electrical system with a line voltage of 480V, a power factor of 0.85, and a load impedance of 8 ohms: The current = √3 x 480V x 0.85 / 8 ohms The result is 89.6 amperes.
