If a phase wire falls on the ground ,if you stand almost on
the line between the neutral grounding point and fault point
you receive the maximum step voltage, if your are feet are
apart along this line.The intensity increases if the fault
is at a short distance from the neutral grounding and you
get a heavy jolt depending on the phase voltage.The step
voltage is equal to phase voltage x distance between your
feet / the distance between fault and neutral ground.
Luckily ,line trips almost instantly.
