What is the difference between eath fault protection &
Restricted Earth fault Protection?

Answer Posted / dinesh kumar

In earth fault protection the feeder or drive is protected
against an earth fault.In restricted earth fault protection
the complete winding of transformer or generator is not
protected against earth fault depending upon the value of
resistance connected in neutral grounding.If the earth
fault occure in the part of unprotected portion of winding
the eart fault relay will not trip

In a power conditoining unit (inverter) of a solar plant when we measure the d.c. current fed by different strings of solar plates to inverter, the current in the negative wire is less almost by 1 ampere to the current in its positive wire say current in positive wire 5 A , then current in negative wire of the same string is 4 A. Since the current entering should be equal to current leaving then why the current is noticably less in negative wire.
