Fault Current Calculator

Fault Current Formula
The following formula is used to calculate a fault current:

\[ FC = \frac{V}{R} \]

Where:

• FC is the fault current in amperes (A)
• V is the voltage in volts (V)
• R is the resistance in ohms (Ω)

Fault Current Definition

A fault current is defined as the maximum current available at any given point in a distribution system. In the event of a fault, the resistance becomes very low, causing the current to spike dramatically.

How to Calculate Fault Current?

To calculate the fault current, simply divide the voltage by the resistance at the point of the fault. This will give you the magnitude of the current that flows through the system under fault conditions.
