Earth Fault
Deear all,
Can anyone make clear to me what is the difference between SENSITIVE EARTH FAULT & RESTRICTED EARTH FAULT PROTECTION? How will we judge that between the two, which protection has to be given to a particular feeder?

Responding to Gupta's 24-Jul-08 (23:41) query:
Sensitive refers to the magnitude, while restricted refers to the zone of protection!

Aseem,
Restricted, as it's name is used for normally Transformer Protection (restricted to internal faults of transformer) & sensitive earth fault for a feeder protection.
For more details google "Earth Fault Protection" & "Restricted Earth Fault Protection".
