How do you protect a power system if a fault occurs?

To limit the extent of the power system that is disconnected when a fault occurs, protection is arranged in zones. The principle is shown in Figure A1.5. Ideally, the zones of protection should overlap, so that no part of the power system is left unprotected. This is shown in Figure A1.6(a), the circuit breaker being included in both zones.
