Zone of Protection System

Each zone of protection, contains one or more components of a power system in addition to two circuit breakers. When a fault occurs within the boundary of a particular zone, then the protection system responsible for the protection of the zone acts to isolate (by tripping the Circuit Breakers) every equipment within that zone from the rest of

What is the protection zone of a power system?

The protection zone of the power system mainly depends upon the rating of the machine, its location, the probability of faults and abnormal condition of the equipment. If there were no overlapping in the protective zone, then the failure occurs in the equipment will not lie in any one of the zones and hence no circuit breaker would be tripped.

Principles of Relay Protection Zones for Electrical Power Systems

The "protection zone" in an electrical power system is defined as the specific region within the system that is monitored and protected from faults by protective relays. This zone is established around each major piece of equipment within the power system. When a fault occurs within any of the protection zones, the protective relays will call on the circuit breakers within
