method of electrical design

Interruption of fault current by a circuit breaker will result in most of the stored energy dissipated within the circuit breaker, the remainder being dissipated during oscillatory surges in the system.

Bad order equipment: Equipment that mis-operated or caused an interruptionresulting from equipment being damaged or deteriorated. Breaker lockout (lockout): The operation that occurs when a circuit breaker is unable to clear a fault. When a breaker locks out, it typically results in a sustained interruption.

The power system contains an appreciable amount of inductance and some capacitance. the energy stored in the system can be considerable
