WHY WE ARE DOING THE EARTHING IN A SYSTEM. SOME PEOPLE ARE
TELLING FOR PROTECTION. WHAT PROTECTION GIVE ME THE CORRECT
ANSWER.
Answer Posted / s.sakthivel
Basically three type of fault develop in the circuits
1, open circuits
2, short circuits
3,loose conection
4,body short
first three electrical fault are directly not distrub humen
and apparatus and last one (body shor) fault is directly
distrub humen and apparatus
so , body short fault time current is to discharge to
ground by the root of earth electrod, so we are addapted
every apparatus earthing system(vanthni@yahoo.com)
