How many zones of protection are there in power system?

Protection Zones When a fault occurs in any of the zone, then only the circuit breaker in that zone trips. Therefore, only a faulty element is disconnected without affecting the rest of the system. Following six categories of protection zones are possible in a system, we apply here a concept of selective coordination.
