Protection Zone in Power System

The protection zone cover the entire power system, and no part of the equipment is left unprotected. It usually consists one or more element of the 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.

Zones of Protection in Power Systems

What is a Protective Zone in Power System? A protective zone is a separate zone that is established around each system element. The significance of such a protective zone is that any fault occurring within cause the tripping of relays which causes the opening of all the circuit breakers within that zone.
