fault current

**fault current**

Fault current refers to the abnormal electric current that flows through a power system when a fault, such as a short circuit or ground fault, occurs. It is significantly higher than the normal operating current and can cause severe damage to electrical equipment if not properly managed. Understanding fault current is essential for designing protective devices like circuit breakers and fuses, ensuring the safety and reliability of electrical systems.
