WHY IS THE EARTH FAULT CURRENT ALWAYS LESS THAN THE NORMAL
CURRENT??
Answers were Sorted based on User's Feedback
Answer / rvg.msceb
earth fault current will be less because the voltage
difference between line and ground is V/1.732 and that of
line to line is V. since the voltage is less, the earth
leakage current will be 57.7% of line to line faults.

Answer / v.selvakumar
we can't say that the fault current lessthan the normal
current ,fault current depend upon the system parameters
i.e resistance ,inductance

Answer / abhishek badh...
Earth fault current is depand upon zero sequence impedence.
impedence is more than e f c is less compared to line
current.

thanks for the reply, but i meant to ask that why is the
earth fault current lesser than other type of fault
currents.

Answer / gaurav
earth falt current current is nothing but the leakage
current and leakage current is alwase less than line or
neutral current.therefore earth fault current is always
less than normal current.
there should not be the common conductor for the earth and
neutral for the safety and to minimizing the ground
potential differances.
