What does AFC mean in UNCLASSIFIED

Availible Fault Current (AFC) is a term used to describe the amount of available electrical current that can flow through a power system during a fault.

AFC must be accurately calculated in order to ensure that people, property, and equipment are kept safe from hazardous levels of electricity. This calculation involves taking into account the load on the system at any given time, as well as other factors such as impedance of circuit breakers and transformers.

AFC calculations are typically used for designing protection relays for systems or for verifying existing protection systems settings are correct. Additionally, these calculations can be used to determine what current will flow through an electrical system when a fault occurs so appropriate measures can be taken beforehand to avoid injury or damage.

It is extremely important to accurately calculate AFC in order to ensure people, property, and equipment are kept safe from hazardous levels of electricity. Any miscalculations or inaccuracies may result in costly repairs or even safety hazards if not addressed immediately.

Miscalculations or inaccuracies with AFC can result in costly repairs or even safety hazards if not addressed immediately. Electricians should take extra care when evaluating potential faults and calculating AFC in order to mitigate any possible risks associated with them.
