Calculate Fault Current (FC)



Formula

The formula to calculate the fault current (FC) is:

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

Where:

Example

Let's say the voltage (\( V \)) is 120 volts, and the resistance (\( R \)) is 0.5 ohms. Using the formula:

\[ FC = \frac{120}{0.5} \]

We get:

\[ FC = 240 \]

So, the fault current (\( FC \)) is 240 amps.

What is Fault Current?

A fault current is defined as the maximum current available at any given point in a distribution system. In the case of a fault, the resistance gets very small, which causes the current to become extremely large. This is crucial for understanding the potential impact of faults in electrical systems and designing protective measures.
