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 / devit patel

please mention the equipment under consider,because earth
falut current directly depens on zero sequance impendance

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.

Answer / minu

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

Answer / vibol seng

I have agreed with answer No 4 any way in distribution
system we have met a lot time (80%) prepaire phase to phase
short circuit.

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.
