We know that, in case if there is a faulty insulation,or
sc, the current is bypassed to earth through the earth wire
that has low resistance.Actually, what will happen to that
current that flows through gnd?In that case,if we come in
contact with that faulty appliance, wont that current flow
through us as we form a closed path by standing in gnd?Is
grounding a safety measure?

Answer / sewagudde
Reason you dont get a shock is that the earth loop path
provides a much lower resistance than the body and
electricity always chooses the path of least resistance.

Answer / debasis
Q. 1> Without a close loop ckt., no current flow.
It should be a close loop path.
Example: If earth fault occured in your home, then current
flowing through earth to transformer neutral(star) point as
the star point of a transformer is grounded.
Q. 2> If you touch the above faulty appliance, idealy,
there should be no effect. But practically, A small current
will flow through body because ur body resistance is in the
range of few kilo to mega ohm. But nothing to be serious.
Thats why we provide earthing.

Hi all, please could anybody give me a suggestion about Electrical designs and calculations .. what text book should i follow as i am a trainee engineer and here work going not so favorable to me so please help me friends .. A small discription about my work which is going here is all about Electrical designs like cable sizing, lighting, lightning, Gensets sizing, motor sizing, transformer sizing, generator sizing, circuit breakers, PDB MCC PCC SLDB MLDB panels, Single line diagrams mainly, substation desings, cable routing and layouts, reactive power compensations, power factor improvement, voltage drop calculations, power generations, power transmission, power distributions all calculations i need .. please please if anybody experienced with this problem and got a solution then please help me .. just i need an apt text book for these all calculations and designs ..
