Introduction
Welcome! This calculator allows you to calculate the generator fault current given a generator power rating, rated voltage, and impedance in base percentage.
Fault currents can occur in a circuit due for several reasons. Knowing this value can provide valuable information for rectifying and diagnosing problems in a circuit. As well as helping you to make appropriate design choices for electrical components.

Explanation
Fault currents occur as a result of low-impedance short circuits. As a generator is an electrical machine, it can occur when a short to ground is created, phases are crossed or other similar scenarios. The magnitude of the generator fault current depends on several technical specifications.
