I have seen 1 video in which a person getting shock while
standing at top of a train,i have 1 question?
why the people sitting in the train doesn't get shock while
that man getting shock from top of the train? How the
earthing of train works?
Answer Posted / kannan
The exact answer is
The rails are earthed at certain points which act as
neutral. Now the train which is on the rails is also at neutral.
A person touching neutral alone doesnt get electrocuted
(passengers inside train).
Person touching neutral as well as overhead line will get
severely electrocuted, so is the case of the person standing
on the train touching the HT overhead line.
As soon as the man touches the line heavy current starts
flowing through his body produces enough heat to burn his
body alive, even though the neutral tends to be at zero
potential which makes the passengers inside or outside
touching the train safe.
Hope this makes good sense..
