Because if the fault occurs outside of the zone means the same fault.
The windings of many medium and small sized transformers are protected by restricted earth fault REF systems. The earth fault protection scheme consists the earth fault relay which gives the tripping command to the circuit breaker and hence restricted the fault current. Restricted Earth Fault Time Delay Earth Fault Trip 50mS Adjustable from 50-500mS Time Delays Accuracy 004 seconds Exceptions Earth Fault Trip 40mS-00 11 x setting 30mS-00 2 x setting 20mS-00 5 x setting Relay Contacts Ratings Frequency 50 OR 60 Hz Maximum Power Consumption 10VA 15VA Nominal AC Nominal. Restricted earth fault protection is provided in electrical power transformer for sensing internal earth fault of the transformer. The restricted earth-fault stage operates exclusively on earth faults inside the area of protection. Also in through fault relay should not operate.
