Difference between Primary Protection and Backup Protection

Primary protection is defined as the initial layer of protection provided in a power system to isolate the faulty elements, if the fault occurs in the zone of relay. It is also known as main

Primary Protection

Every zone identified for protection will have a suitable protection specified. If a fault occurs in that zone, it is the duty of the relays in that zone to identify and isolate the faulty element in that zone. The relay

Types of Protection | Primary Protection | Back-up

If a fault occurs on any line, it will be cleared by its relay and circuit breaker. This forms the primary or main protection and serves as the first line of defence.
