Protection is commonly provided by (Circuit Breakers) as follows: • Protection against Short Circuit • Protection against Over Current • Other Types of Protection (Try to remember some of them)

Faults that are commonly occurring are (Short Circuit) as follows: • Line – Earth (@ 80% of faults occurrence) • Line – Line (@ 15% of faults occurrence) • Three Line (@ 5% of faults occurrence)
